Sorry, I have not yet made the move to DXP. Keep in mind that my library
components do not have keep-outs defined for any footprints. I've designed them so
that Protel's clearance constraint rule ends up using the slik-screen traces as it's
guide. So far, in my setup, P99se seems to ignore the component's name & #, unless
they are on another layer other than the silkscreen.
A good method to use this technique to your advantage would be to make a second
clearance rule related to silkscreen traces without modifying the current 20 mil
default, making sure it deals only with the footprint's keepout layer.
Be sure your U shaped component just has no keepout defined & you should be able
to get stuff inside the 'U'. To really squeeze things in, try the smd stuff in my
library.

Brian,
In 2004 or more recent DXP versions, did Altium ever fix the fact
that the clearance check includes all reference designators and other
attributes within the footprint boundary check? Such that if you had a long
attribute string it made the footprint clearance check impossible.

Design it like all of the components in my publicly available library, where
the silkscreen defines the outer & inner edges of where the component
surfaces meet the PCB. Shrink the component-component clearance to 1 mil,
or 0 mil. This will allow you place, for example, some caps & resistors
right up to & under some areas of a large PCB mounted RCA jack, but, it will
not allow you to place components too close where the silk screen area may
touch each other. Note that my library was intentionally designed like this
for creating hand-held electronic devices where mounting area may be super
constrictive.
