Hi, I am trying to model this real world situation into XFML and/or
FacetMap XML and consequently into faceted browsing navigation on the
web page.

Browsing through job offerings can be by job location(s), job work
area(s) and salary.

As I found out: A resource can not map to two or more headings in the
same taxonomy.

If so, it is impossible to say that one job takes place in two
different locations and job description can not be in two or more
predefined work areas (say "java programmer" and "information architect").

I just started exploring things in this area, so maybe I am
conceptually wrong.

What do you say?
