From an XSL processing standpoint, it doesn't matter if the root is
"mods" or "modsCollection".

I use <apply-templates select="descendant-or-self::mods:mods"/>,and it
processes as many mods records as there are, skipping modsCollection if
need be.

Ok, I see.

Mods defines both the "mods record" and "mods collection"  where the
latter
is a collection of records.

(So <mods> or <modsCollection> can be the root, for a mods record or
mods
collection respectively.)

A solution (to the apparent complexity and confusion that this causes)
is to
define a separate schema for modsCollection.

We did discuss this long ago and decided it wasn't necessary, but I
wouldn't
object to revisiting this.  You could propose it for version 4.

Another suggestion has been to dissalow <mods> as a root, so that
<modsCollection> would wrap even a single mods record. I would  oppose
this
approach but would not oppose a  separate schema.
