In my muse.xml, I have a set of resources that the app will initially
load. I also have a ServiceGroup that will be loaded, and will used to
hold references to the other resources. I would like to set membership
rules on my ServiceGroup so that it only holds references to certain
resource types, based on the resource names. But, the current
design/implementation of MembershipContentRule seems to filter resources
based on their property names, which doesn't seem useful to me. Is
there a simple way to non-programmatically set a rule to filter by
resource name? If I have to do this programmatically, how would I do
this? Just extend and override
SimpleMembershipContentRule.isMatch(EPR)?
