RE: xsl:result-document and Saxon serializer problems

I suspect the answer to questions 1 and 2 lies in the bits of the stylesheet
that you haven't shown us. 

The answer to question 3 is that you seem to have misunderstood
exclude-result-prefixes:

(a) it only affects the behavior of literal result elements, and I don't see
any literal result elements in your code

(b) its scope is static rather than dynamic. If you put the attribute on an
element such as xsl:result-document, it only affects literal result elements
that are physically contained within that xsl:result-document element.

To work out where the "thin air" attributes are coming from, I can assure
you Saxon isn't making them up! You might find that the -T trace option
helps with your debugging.
