[Bug 4031] Final Result Trees

http://www.w3.org/Bugs/Public/show_bug.cgi?id=4031





------- Comment #10 from mukul_gandhi@yahoo.com  2006-12-16 05:28 -------
Thanks a lot for clarification. As per your clarifications below, I think, the
paragraph I cited below from Section 19 could be written as:

"A final result tree can be created explicitly, by evaluating an
xsl:result-document instruction. A final result tree is also created implicitly
if no xsl:result-document instruction is evaluated."

(I have dropped the part - "or if the result of evaluating the initial template
is a non-empty sequence")

This I think will be more clear to readers.

I would also like to see your comments (Comment #5) appear as editorial
changes. 

Regards,
Mukul
