DOCBOOK: is docbook appropriate for resumes?

Greetings -

I just updated my resume for the umpteenth time.  I keep the master in
plain text, then made a HTML version, and then a pdf version.  I've never
used docbook, but from what I've read about it so far, it seems like
storing it in docbook might be the way to go.

I only use a few formatting elements:  3 different font sizes, 2 font
sets, bold face, and one section uses 2 columns.

Would docbook be the right way to go?

TIA.
