The <* is an operator that I added to the filter. It mean that the
attribute can have multiple values and is therefor a set. This set
must then be a subset of the right hand site. RFC 112 elaborates this
further. I tried to get these operators (subset/superset) part of the
spec but it was rejected. However, OBR needed them to model mandatory
directive. There you have a set of attribute names that all needed to
be present.
In this case, mandatory: is the set of attribute names in the
expression, and we verify that they are all there with <* operator.
Again, these operators did not make for the next OSGi release.
Hope this helps, RFC 1112 can be found here:

Kind regards,

Hello,
today I ran into a problem when generating my repository.xml with
bindex:
Spring-core has a manifest entry:
org.eclipse.core.runtime;resolution:=optional;common=split
Bindex will generate the following <require> entry:
<require extend='false'
filter='(&(package=org.eclipse.core.runtime)(version>=0.0.0)
(comm
on=split)(mandatory:<*common))'
multiple='false' name='package' optional='true'>
Import package org.eclipse.core.runtime
</require>
The problem is the
mandatory:<*common
entry - this will cause an org.osgi.framework.InvalidSyntaxException
in
the org.eclipse.osgi.framework.internal.core.FilterImpl class for the
mandatory: input.
Why does bindex add this attribute and what does it stand for?
Thanx in advance for any help,
Michael
