I'll note that my original architecture document[1] contemplated two
kinds of "add-on" profiles:

  - ExtensionProfiles could register *new* kinds of steps, as well as
    making non-destructive insertions to the configuration created by a
    baseline profile.

  - DeltaProfiles essentially captured line-level diffs to a "baseline"
    profile.

I think there is room for both, where we get away from the need to make
EPs the "current" profile in order to use them.  DeltaProfiles could be
"applied" by patching a snapshot, and then installing the snapshot as a
new baseline.

Because not all the files being patched are XML, I don't think we can or
should rely on XSLT:  diff might be enough.
