xsl:result-document creates a complete document each time it is invoked.
It's supposed to be an error to write to the same URI more than once, but
Saxon isn't currently detecting this error (it simply overwrites the file).

xsl:result-document isn't designed to append - that would make the results
dependent on order of evaluation. If you want to create two output files,
you need to create one of them completely, then the other completely, you
can't interleave them. This means structuring your stylesheet differently.

It's possible that you could use (abuse!) Saxon's OutputURIResolver to
append to existing files, but it's not something I would recommend.
