I don't think I understand from this what the specification of a package
that would Provide wims-extra would be.

A virtual package exists to satisfy a dependency on a specific piece of
functionality.  For example, ispell needs a dictionary, packages need to
depend on a mail transport agent, and Emacs add-ons are only useful if
some version of Emacs is installed.

What dependency is wims-extra providing?  It seems like there is a general
server (wims) and a variety of different modules for it, but I'm not
seeing where anything needs to depend on the wims-extra virtual package.
Wouldn't people just install the wims server and then whatever modules
they want to use, sort of like installing an Apache server and whatever
Apache modules they wish to use?

The description, in particular, sounds like a grab bag of different

so I don't know what would be guaranteed about a package that Provides
wims-extra.  It seems like all that would tell me is that it works with
wims, which isn't something one has to use a virtual package to do.
