+ * takes no parameters and the type is immutable; hence only a default instance

+ * However, the SafeStyle string *must be HTML-attribute-escaped* before
+ * interpolation.
+ * <li>Interpolated as the content of a {}-wrapped block within a stylesheet.
+ * '<' characters in the SafeStyle string *must be CSS-escaped* before
+ * interpolation. The SafeStyle string is also guaranteed not to be able
+ * to introduce new properties or elide existing ones.
+ * <li>Interpolated as the content of a {}-wrapped block within an HTML
+ * <style> element. '<' characters in the SafeStyle string
+ * *must be CSS-escaped* before interpolation.
+ * <li>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(mlourenco): 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)

+ *
+ * Instances of this type must be created via the factory method

+ * is immutable; hence only a default instance corresponding to the empty string
+ * can be obtained via constructor invocation.
+ *
+ * A SafeStyleSheet's string representation can safely be interpolated as the
+ * content of a style element within HTML. The SafeStyleSheet string should
+ * not be escaped before interpolation.

+ * Values of this type must be composable, i.e. for any two values

+ * {@code goog.html.SafeStyleSheet.unwrap(styleSheet1)} must end in
+ * "beginning of rule" context.
+
+ * A SafeStyleSheet can be constructed via security-reviewed unchecked
+ * conversions. In this case producers of SafeStyleSheet must ensure themselves
+ * that the SafeStyleSheet does not contain unsafe script. Note in particular
+ * that {@code &lt;} is dangerous, even when inside CSS strings, and so should
+ * always be forbidden or CSS-escaped in user controlled input. For example, if

+ * inside a CSS string, it would break out of the context of the original

+ * A string that is safe to use in URL context in DOM APIs and HTML documents.
+ *
+ * A SafeUrl is a string-like object that carries the security type contract
+ * that its value as a string will not cause untrusted script execution
+ * when evaluated as a hyperlink URL in a browser.
+ *
+ * Values of this type are guaranteed to be safe to use in URL/hyperlink
+ * contexts, such as assignment to URL-valued DOM properties, in the sense that
+ * the use will not result in a Cross-Site-Scripting vulnerability. Similarly,
+ * SafeUrls can be interpolated into the URL context of an HTML template (e.g.,
+ * inside a href attribute). However, appropriate HTML-escaping must still be
+ * applied.
+ *
+ * Note that, as documented in {@code goog.html.SafeUrl.unwrap}, this type's
+ * contract does not guarantee that instances are safe to interpolate into HTML
+ * without appropriate escaping.
+ *
+ * Note also that this type's contract does not imply any guarantees regarding
+ * the resource the URL refers to. In particular, SafeUrls are <b>not</b>
+ * safe to use in a context where the referred-to resource is interpreted as
+ * trusted code, e.g., as the src of a script tag.
+ *
+ * Instances of this type must be created via the factory methods
+ * ({@code goog.html.SafeUrl.fromConstant}, {@code goog.html.SafeUrl.sanitize}),
+ * etc and not by invoking its constructor. The constructor intentionally
+ * takes no parameters and the type is immutable; hence only a default instance
