[XalanJ2] Proposed changes for DocumentFrag

[Gary L Peskin <ga...@firstech.com>]

I'd like to make the following changes to allow a DocumentFragment to be
treated like a Document.  This will simplify the implementation of the
nodeset extension and will also be useful for a future version of XSLT
if result tree fragments become automatically convertible into
nodesets.  This does _not_ change the handling of result tree fragments
under the current implementation.  They still throw an error if you
attempt to convert them to nodesets without using the extension.

Here are the changes I'd like to make:

Scott or someone, please let me know if you agree and I can commit the
changes.  Otherwise, let's discuss.

TIA,
