-/**
- * A string-like object which represents a sequence of CSS declarations
- * ({@code propertyName1: propertyvalue1; propertyName2: propertyValue2; ...})
- * 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.
- *
- * SafeStyle's string representation can safely be:
- * <ul>
- *   <li>Interpolated as the content of a *quoted* HTML style attribute.
- *       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().
- *
- * The following example values comply with this type's contract:
- * <ul>
- *   <li><pre>width: 1em;</pre>
- *   <li><pre>height:1em;</pre>
- *   <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)
- *   <li><pre>1em</pre> (missing an attribute name, which provides context for
- *       the value)
- * </ul>
