Eric,
Currently there are ~130 items in the colorList. I did consider pattern
restriction, but was trying to see if there is a simpler way (I am not very
well versed in XML Schema or XPath for that matter).
Using normalized string ( xs:token) seems like a good idea; xs:string was
a tighter spec forcing the user to use values in the enumeration list.
Thanx for the response. .
