The issue is, I need to determine whether or not a given fragment
conflicts with the existing host or other fragments or else I cannot
attach it. Currently, the approach I take is quite simplistic, which is
just requiring any overlapping Import-Package or Require-Bundle to be
identical (i.e., I allow that, anything else I reject attaching the
fragment).
If/when necessary, I contemplate getting around this by just trying to
satisfy all dependencies and just look for interesting candidates on
overlapping ones, but it doesn't seem necessary now.

I don't know how imported the conflict detection mentioned below is,
but I wrote a bunch of code to merge groups of package imports from
various sources and throw helpful exceptions identifying any conflict
together with the original sources of the conflict. Merging computes
the intersection of version ranges and squares up other attributes and
directives. Currently, this is in the GPL portion of dm Server, but if
it would help, I could look into migrating it down into the Apache
licensed util area for Felix to reuse or fork.
If and only if you are comfortable looking at GPL source code, see [1]
and the other classes in the same directory. If you're not
comfortable, I'm happy to answer any questions here.

----------------------------------------
You mention that your fragments import nearly the same packages, Be
aware that Felix fragment import conflict detection currently
requires overlapping imports of fragments to be identical (i.e., same
package, version range, attributes, and directives). If not, then it
will not allow it.
