Re: [p2-dev] Generating multiple <update> elements for a <unit> (to hand

[Pascal Rapicault <pascal@xxxxxxxxxxxxx>]

This is supported by using an p2ql expression in the update descriptor
Here is an example of such an expression:

providedCapabilities.exists(pc | pc.namespace == 
'org.eclipse.equinox.p2.iu' && (pc.name == 'B' || pc.name == 'C'))
