It appears that our discussion in this thread quickly goes into direction
of comparing different analogies to the problems discussed. Before we
get to far, I'd like to revisit some higher-level points.

Dave, it seems like your proposal has three major aspects:

1. You claim that using one syntactic elements for both
requirements and alternative selection is good.

2. You claim that it's often desirable to express
"select this alternative is either <feature1>value1 or ...
... or <featureN>valueN" is in properties.

3. You claim that alternative selection should consider
only explicitly specified properties.

Is that correct, and are there any other important points I've miseed?
