Re: [cross-project-issues-dev] Platform filters and the aggregator

[Thomas Hallgren <thomas@xxxxxxx>]

Hi Stephan,

Would it be possible for you to simply write one single declaration like 
this:

     <plugin
         id="org.eclipse.objectteams.otequinox.sunjvm"
         os="linux,solaris,win32"
         ... />

?

I'm not sure what the problem really is since the aggregator doesn't 
care much about your feature.xml. It will only consult the p2 meta-data.

HTH,
Thomas Hallgren

PS.
What's the relevance of the fragment="true" in a feature plugin 
declaration? I know it can be entered, but does it have any purpose?
