So I have large XML Schema 1.0 that has all it's elements/type/etc defined in in no namespace. (null namespace, unqualified however you refer to it)

Does someone have a tool/xslt that can force all elements and attributes defined in the schema into a qualified/prefix namespace? I have a deep understanding of schema and xslt and can make any modifications if the tool if it's a partial fix. I did some searching around, but couldn't find anything out there and I couldn't find anything in XML Spy/Stylus Studio that might help me do this quickly.

I have to assume this need has came up before at some point, so I was hoping that someone had something out there to automate it.

Thanks!
