Apart from the doc change, the patch is ok now.

The preceding text says "Four schema are predefined, two schemata are 
variable", then we add "env" to both lists? That doesn't make much sense 
to me.  Surely it's just a "predefined schema"?  In any case that text 
should be updated.

I'd rephrase that a bit here.  This is the description of the scheme
itself, so this should be something along the lines of "utilizes the
current environment ..." and "Right now only valid for db_home, see xref
linkend="ntsec-mapping-nsswitch-home"...

However, there's something strange going on, see below.

I think drop wrapping in <term> here should fix the error below.  It's 
not valid docbook here.

There's something wrong here. Building the docs, I get these new error

It looks like this has something to do with the <term> expression?

Jon, do you have an idea?
