Perhaps this is just a minor Syntax thing . . . I would expect this:

/project/scm@class

To return all the SCM class attribute in each job.

Instead, all jobs (both with and without scm second) are put into "<!-- not assigned -->"

Note that scm[@class] seems to search correctly, I'm just not sure how to get the value to display.

AWESOME plugin BTW: a much needed addition to Slicing since adding to it seems hard.
