attribute problem.

I have the following XML:

<Color colorNo = "1">RED</Color>

And I want to write a schema for it, now the latest XML Schema draft says
that it should be done something like this (I may have this slightly
wrong, I have not got my notes on me!... also I know xerces does not
support this):

<element name="color">
	<complexType>
		<simpleContent>
			<extension base = "string"/>	
		</simpleContent>
		<attribute name = "colorNo" type = "string">
	</complexType>
</element>

Now the April draft did not define <simpleContent>, so I am just wondering
if it is possible to represent this schema in a way that the current
version of XERCES supports? Also does anyone know when a version of XERCES
supporting a more recent draft, or even the candidate release will be
ready?

Thankyou in advance,

Hi, Timothy, 
I believe it should be:
<element name='Color'>
    <complexType base=string' derivedBy='extension'>
        <attribute name='colorNo' type='string' />
    </complexType>
</element>
