Thanks, Nick.

Please accept also this follow-up, then.  Note two things:

1. xmlcatalog.1 will be generated automatically from xmlcatalog_man.xml
   upon "make -C doc docs" once libxml2 is configured with
   --enable-rebuild-docs (hence I expect I don't need to care about that)

2. I don't see any hook to refresh xmlcatalog_man.html in the build system,
   and indeed, that file seems to be quite stale -- I suggest either
   adding a hook to have that file (and possibly more like that) refreshed
   (leveraging html/docbook.xsl from DocBook distribution) or drop that
   (and possibly more) altogether
