That dawned on me about 30 seconds after I hit send.

link is very close to olink.
xref is not but lets us customize: 
(http://www.sagehill.net/docbookxsl/CustomXrefs.html)

So that I don't have another senior moment.

The options I'm aware of are:
olink   - external links to other docs in this collection
link    - hyperlinks within this doc
ulink   - links to anywhere, uses URIs
xref    - links within this document, template-able

I like that xrefs lets us insert things like Page # and Chapter # in the 
output. I like pg#s in pdf links.


Should, for the moment, we try to use one or the other so that we don't 
add to the tag proliferation, or does it matter?  I can see cases for each.

Your thoughts?
