+ * will restrict <code>foo</code> to a truthy value.
+ *
+ * The compiler has an option to disable asserts. So code like:

+ * </code>
+ * will be transformed into:
+ * <code>
+ * var x = foo();

+ * The compiler will leave in foo() (because its return value is used),

+ * This file provides type-safe wrappers for DOM APIs that can result in
+ * cross-site scripting (XSS) vulnerabilities, if the API is supplied with

+ * safe wrappers consume values of types from the goog.html package whose

+ *
+ * Hence, a program that exclusively uses the wrappers in this file (i.e., whose

+ * guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo
+ * correctness of code that produces values of the respective goog.html types,
+ * and absent code that violates type safety).
+ *
+ * For example, assigning to an element's .innerHTML property a string that is
+ * derived (even partially) from untrusted input typically results in an XSS
+ * vulnerability. The type-safe wrapper goog.html.setInnerHtml consumes a value
+ * of type goog.html.SafeHtml, whose contract states that using its values in a
+ * HTML context will not result in XSS. Hence a program that is free of direct
+ * assignments to any element's innerHTML property (with the exception of the
+ * assignment to .innerHTML in this file) is guaranteed to be free of XSS due to
+ * assignment of untrusted strings to the innerHTML property.

+ *
+ * Instances of this type must be created via the factory method
+ * {@code goog.html.SafeScript.fromConstant} and not by invoking its
+ * constructor. The constructor intentionally takes no parameters and the type
+ * is immutable; hence only a default instance corresponding to the empty string

+ *
+ * A SafeScript's string representation can safely be interpolated as the

+ * Note that the SafeScript might contain text that is attacker-controlled but
+ * that text should have been interpolated with appropriate escaping,

+ * conversions. In this case producers of SafeScript must ensure themselves that

+ * A string-like object which represents a sequence of CSS declarations

+ * and that carries the security type contract that its value, as a string,
+ * will not cause untrusted script execution (XSS) when evaluated as CSS in a
+ * browser.
+ *
+ * Instances of this type must be created via the factory methods
+ * ({@code goog.html.SafeStyle.create} or
+ * {@code goog.html.SafeStyle.fromConstant}) and not by invoking its
+ * constructor. The constructor intentionally takes no parameters and the type
+ * is immutable; hence only a default instance corresponding to the empty string
+ * can be obtained via constructor invocation.
+ *
+ * A SafeStyle's string representation ({@link #getTypedStringValue()}) can
+ * safely:
+ * <ul>
+ *   <li>Be interpolated as the entire content of a *quoted* HTML style
+ *       attribute, or before already existing properties. The SafeStyle string
+ *       *must be HTML-attribute-escaped* (where " and ' are escaped) before
+ *       interpolation.
+ *   <li>Be interpolated as the entire content of a {}-wrapped block within a
+ *       stylesheet, or before already existing properties. The SafeStyle string
+ *       should not be escaped before interpolation. SafeStyle's contract also
+ *       guarantees that the string will not be able to introduce new properties
+ *       or elide existing ones.
+ *   <li>Be assigned to the style property of a DOM node. The SafeStyle string
+ *       should not be escaped before being assigned to the property.
+ * </ul>
+ *
+ * A SafeStyle may never contain literal angle brackets. Otherwise, it could
+ * be unsafe to place a SafeStyle into a &lt;style&gt; tag (where it can't
+ * be HTML escaped). For example, if the SafeStyle containing
+ * "{@code font: 'foo &lt;style/&gt;&lt;script&gt;evil&lt;/script&gt;'}" were
+ * interpolated within a &lt;style&gt; tag, this would then break out of the
+ * style context into HTML.
+ *
+ * A SafeStyle may contain literal single or double quotes, and as such the
+ * entire style string must be escaped when used in a style attribute (if
+ * this were not the case, the string could contain a matching quote that
+ * would escape from the style attribute).
+ *
+ * Values of this type must be composable, i.e. for any two values
+ * {@code style1} and {@code style2} of this type,
+ * {@code goog.html.SafeStyle.unwrap(style1) +
+ * goog.html.SafeStyle.unwrap(style2)} must itself be a value that satisfies
+ * the SafeStyle type constraint. This requirement implies that for any value
+ * {@code style} of this type, {@code goog.html.SafeStyle.unwrap(style)} must
+ * not end in a "property value" or "property name" context. For example,
+ * a value of {@code background:url("} or {@code font-} would not satisfy the
+ * SafeStyle contract. This is because concatenating such strings with a
+ * second value that itself does not contain unsafe CSS can result in an
+ * overall string that does. For example, if {@code javascript:evil())"} is
+ * appended to {@code background:url("}, the resulting string may result in
+ * the execution of a malicious script.
+ *
+ * TODO(user): Consider whether we should implement UTF-8 interchange
+ * validity checks and blacklisting of newlines (including Unicode ones) and
+ * other whitespace characters (\t, \f). Document here if so and also update
+ * SafeStyle.fromConstant().
+ *

+ *   <li><pre>width: 1em;height: 1em;</pre>
+ *   <li><pre>background:url('http://url');</pre>
+ * </ul>
+ * In addition, the empty string is safe for use in a CSS attribute.
+ *
+ * The following example values do NOT comply with this type's contract:
+ * <ul>
+ *   <li><pre>background: red</pre> (missing a trailing semi-colon)
+ *   <li><pre>background:</pre> (missing a value and a trailing semi-colon)

+ * @fileoverview Message/plural format library with locale support.
+ *
+ * Message format grammar:
+ *
+ * messageFormatPattern := string ( "{" messageFormatElement "}" string )*
+ * messageFormatElement := argumentIndex [ "," elementFormat ]
+ * elementFormat := "plural" "," pluralStyle
+ *                  | "selectordinal" "," ordinalStyle
+ *                  | "select" "," selectStyle
+ * pluralStyle :=  pluralFormatPattern
+ * ordinalStyle :=  selectFormatPattern
+ * selectStyle :=  selectFormatPattern
+ * pluralFormatPattern := [ "offset" ":" offsetIndex ] pluralForms*
+ * selectFormatPattern := pluralForms*
+ * pluralForms := stringKey "{" ( "{" messageFormatElement "}"|string )* "}"
+ *
+ * This is a subset of the ICU MessageFormatSyntax:
+ *   http://userguide.icu-project.org/formatparse/messages
+ * See also http://go/plurals and http://go/ordinals for internal details.
+ *
+ *
+ * Message example:
+ *
+ * I see {NUM_PEOPLE, plural, offset:1
+ *         =0 {no one at all}
+ *         =1 {{WHO}}
+ *         one {{WHO} and one other person}
+ *         other {{WHO} and # other people}}
+ * in {PLACE}.
+ *
+ * Calling format({'NUM_PEOPLE': 2, 'WHO': 'Mark', 'PLACE': 'Athens'}) would
+ * produce "I see Mark and one other person in Athens." as output.
+ *
+ * OR:
+ *
+ * {NUM_FLOOR, selectordinal,
+ *   one {Take the elevator to the #st floor.}
+ *   two {Take the elevator to the #nd floor.}
+ *   few {Take the elevator to the #rd floor.}
+ *   other {Take the elevator to the #th floor.}}
+ *
+ * Calling format({'NUM_FLOOR': 22}) would produce
+ * "Take the elevator to the 22nd floor".
