There are several ways to do it; you can concatenate the two strings and parse them out on the other side, or rather than using a flat XML cursor, you can construct a hierarchical document with the DOM - it's slower, but it can reflect the entirety of a schema in a string that can be parsed cleanly.

And why can't you build an XML document that contains the error message?
