[wp-hackers] same taxonomy on two different object types?

[andré renaut]

I am afraid you can't

for a plugin development, i made my own taxonomy (based on wp ones) and had
to face strange behavior when slug had the same value for the same term in
different taxonomies.

i hope that in a future release (see http://codex.wordpress.org/Version_2.8),
MPTT <http://codex.wordpress.org/index.php?title=MPTT&action=edit> for
hierarchies will be implemented with a true Taxonomy API in an Object
Oriented way.
