+ <p>While support for CSS as a whole is not required of
+ implementations of this specification (though it is encouraged, at
+ least for Web browsers), some features are defined in terms of
+ specific CSS requirements.</p>
+
+ <p>In particular, some features require that a string be
+ <dfn id="parsed-as-a-css-color-value">parsed as a CSS <color> value</dfn>. When parsing a CSS
+ value, user agents are required by the CSS specifications to apply
+ some error handling rules. These apply to this specification also.
+ <a href="#refsCSSCOLOR">[CSSCOLOR]</a> <a href="#refsCSS">[CSS]</a></p>
+
+ <p class="example">For example, user agents are required to close
+ all open constructs upon finding the end of a style sheet
+ unexpectedly. Thus, when parsing the string "<code title="">rgb(0,0,0</code>" (with a missing close-parenthesis) for
+ a color value, the close parenthesis is implied by this error
+ handling rule, and a value is obtained (the color 'black').
+ However, the similar construct "<code title="">rgb(0,0,</code>"
+ (with both a missing parenthesis and a missing "blue" value)
+ cannot be parsed, as it closing the open construct does not result
+ in a viable value.</p>
+
+ </dd>
+
</dl><p>This specification does not <em>require</em> support of any
particular network protocol, style sheet language, scripting
language, or any of the DOM specifications beyond those described
