I've seen this problem on several projects. I think the best fix is to use a schema-agnostic processor. With a schema-agnostic processor, you can work with content whether it validates or not. This is often handy, as it's easier to fix the invalid documents in the processing environment than outside of it. For example, inside the processing environment I can fix the problem by writing an XQuery. Disclaimer: I work for Mark Logic, which sells a schema-agnostic XML content server.
