It depends on what your definition of "applied" is.
The intent behind my comment is that keys do apply to added documents.
I didn't mean to make any determination of *when* they are computed.

Sure. I don't think this meaningfully contradicts me.

The "only use matched nodes in same doc as the context" bug is one I
also had to fix in 4XSLT back then. You might want to try my code from
the article cited to check whether Xalan complies. Saxon does agree
with 4XSLT, and the spec, on this.
