You are almost half right. This is not happening so that the result 
be valid to the source's DTD. Most of the time that would be a bad 
idea and undesirable.

Rather, you are apparently doing a near-identity transformation, in 
which most of what the stylesheet is doing is simply copying the 
input to the result. But your DTD contains attribute declarations 
that provide default values to some of the attributes in your 
document. Accordingly, when your DOCTYPE declaration is in place, the 
parsed document (the tree-shaped thing on which the transform 
actually operates) contains the attributes -- which then get copied 
along with the rest.

If you want these not to be there, simply write your stylesheet to 
suppress them instead of copying them.

Depending on how your identity transformation is constructed, this 
can be as easy as:

<xsl:template
  match="@isFloatColumnFooter | @whenResourceMissingType | 
@isIgnorePagination"/>

Alternatively, ensure that the DTD is not used by removing or 
commenting out the DOCTYPE declarations in your input; as you've 
found, the defaulted attributes won't then be copied to the result. 
But the first solution is less of a hack.

Cheers,
Wendell
