Yes.

No.  The internal declaration subset is considered an aspect of the syntax 
of the input document, and it is not preserved in the data model for XPath 
upon which XSLT operates.  Therefore, there is no way to copy that 
information to the result tree, which is also constructed using the data 
model for XPath.  Without representation in the data model, there is no way 
your input can be preserved for the output.

You have two choices:

(1) - create a mini-DTD that contains your internal declaration subset plus 
a parameter entity reference to your main DTD
 - you can then point to the mini-DTD in your <xsl:output>, without an 
internal declaration subset, and the resulting file will find those 
declarations and the main body through the parameter entity reference

(2) - craft your own resulting internal declaration subset using a text 
node and disable-output-escaping.

I hope this helps.
