"The attributes on xsl:output elements affect only the main result
document." [http://www.w3.org/TR/xslt11/#multiple-output]
For chunked output dbxsl makes use of one of the following elements,
depending on available xslt-extensions:
<exsl:document>, <saxon:output> or <xalanredirect:write>.
XSLT 1.1 WD suggests the similar <xsl:document>.

IMO, you need to specify omit-xml-declaration="yes" in just those
mentioned elements so they apply to every single written junk. They are
used inside chunker.xsl in the named template write.chunk.

According to
http://saxon.sourceforge.net/saxon6.5/doc/xsl-elements.html#xsl:document
the use of xsl:output attributes should be possible, e.g. for
<saxon:output>.

Concerning the main result document there should be no need to modify the
xsl:output's in imported stylesheet fragments because they are already
overridden by your customization layer.

HTH,
Steffen.
