Joe Kesselman deleted comment on XALANJ-2818:
---------------------------------------
was (Author: JIRAUSER285361):
If you ask for the descendent-or-self axis, that will include all descendents
of the reference node, and all nodes in that document are descendents of that
document node. Working as designed.
If all you want to count is the document node,
select="count(document-node())"
Is effectively counting on the self:: axis.
> document-node() matches/selects more than document nodes

> This is a bug report against the XSLT 3.0 development branch of Xalan.
> I find that document-node() matches/selects a lot more than just document
> nodes.
