Hi Joe,

I'd never heard of it before today either - problem is BS7666 is an 
'official' UK Gov Schema and it conforms to the w3 specs.  As a short-term 
workaround we'll hack the xsd to use the 'normal' Reg Exp notation like you 
suggest - mid-long term I think we'll be abandoning MSXML for this product 
and looking at another method (.NET/Java/Xerces/whatever .. *sigh*)

Thanks!

Carl
