For better or for worse, the emerging XML architecture DOES elevate schemas, validation and ty*e declarations above other "XML processing applications". For example SOAP and WSDL implementations use XML schema types to do type conversions. WSDL actually uses XML Schema as some kind of abstract type definition system (completely distinct from its use as an XML validation tool). XSLT 2.0 and XPath 2.0 are also going to use information from the schema. These specifications do not build on XML Schema for its validation facilities. They do for its t*** system. So flaws in that system will eventually become material to all XML users. Some future applications may not deal with element labels (or ulabels) at all. They will deal with t*** names. -- Take a recipe. Leave a recipe. Python Cookbook! http://www.ActiveState.com/pythoncookbook
