Issue #728 - Permit cardinality:=multiple on Require-Capability, as per the OSGi spec

Signed-off-by: Tim Ward timothyjward@apache.org
Shouldn't the code test that the cardinality directive only has legitimate values? It seems the code allows any value for cardinality. resolution should also test for the allowed values.  effective is fairly open ended so you can't check its values. But even for filter, the value could be checked to ensure it is a well formed filter expression.
