Rationale for content model of definition list entry

[Kristen James Eberlein <kris@eberleinconsulting.com>]

I was asked about the content model for definition lists this past week.

Why does the content model for <dlentry> allow multiple instances of 
<dt>? I can understand multiple instances of <dd> -- a term often has 
multiple definitions -- but a use case for multiple (primary) terms 
eludes me.

FWIW, the content model for <dlhd> only permits zero or one <dthead> and 
zero or one <ddhd>.
