DOCBOOK: Optional parameters in funcsynopses?

[Lars Torben Wilson <torben at php dot net>]

Hi out there...

I've searched the net and these mailing lists' archives and haven't
been able to find a canonical answer for this question. I'm moving a
large number of DocBook 3 files to DocBook 4, and have run into the
tightened content model of <parameter>; i.e., it no longer contains
<optional> or other such tags. This is, I presume, for an excellent
reason; however, I wonder what the current proper way to express the
following would be?

  int somefunc(arg1 [, arg2 [, arg3]])

Or am I missing something fundamental? Thanks for any hints.
