Description
The functx:remove-attributes-deep function removes attributes from a sequence of elements and all of their descendants. The $names argument is a sequence of strings that represent attribute names to remove. Prefixes can (and must) be used in the $names values for attributes that are prefixed in the input documents. You can also specify wildcard values "*", "*:" and ":*" in the second argument. See the description for functx:name-test for details.
Note: this function is intended to change the way elements and attributes appear in the results of a query, not to update them in an XML database. To update your XML database, you should use the implementation-specific update functions of your processor.
