One way is: Write your own schema document for the 'theirs' namespace, assign the type of your choice to 'foo', and point your software at your schema document for the namespace. Plus: very simple. Minus: you end up duplicating all of their declarations, and if they perform maintenance you don't get those fixes. (Unless you automate the production the schema document by writing a simple transform to take their schema document and replace the appropriate element declaration, leaving everything else as is.) Plus and/or minus: if you do it this way, the type you provide does not need to be either a restriction or an extension of xs:string. That's a distinct plus, except in cases where it's a distinct minus. And vice versa. YMMV and you have been warned. Void where prohibited by law, etc etc etc. hth -- **************************************************************** * C. M.
