Hi Bud,

I should point out that our schema validation service is simply a web  =

frontend to the Xerces-J Schema Validator (this used to be made clear  =

on the web page, but it seems that notice has gone AWOL - I'll get  
that fixed).

A quick look at the schema spec suggests that Xerces is wrong on this  =

point:

"The - character is a valid character range only at the beginning or  
end of a =B7positive character group=B7."

regards,

Paul
