  How about disabling validation in conditions altogether? Validation
is a problem espesially for dynamically extended features. For
example, I have a feature that detects all installed versions of a
tool on the client machine, and extends the feature <tversion> with
the detected versions. Some projects might require conditions such as
<tversion>2.0:<define>T_2, which produce validation errors when run on
machines that do not have tool version 2.0 installed. Instead, it
should simply evaluate to 'false', when <tversion> is not 2.0.
