RE: saxon:output doctype inherits xsl:output doctype

I don't think there's a solution to this, though it's so long since I worked
with Saxon 6.5.5 that I may have forgotten something. I'd suggest moving to
Saxon 8.x and xsl:result-document, which gives you much more control; you're
also on much more secure ground using a standard XSLT 2.0 feature rather
than a vendor extension in a 1.0 product that isn't being developed any
further.

(The issue here is that doctype-system and doctype-public, unlike other
serialization attributes, have no way to specify the default value "absent"
by means of explicit syntax. The problem still exists in 2.0 with
xsl:result-document, but you can avoid it by using named output
definitions).
