Close, the idea was that I want to read all "foobar-value"s from all
modules that have that tag set.

Yes, I'm aware of that, but I'm not sure if it supports the above
clarified idea which would use non-namespace "foobar-value" to fetch all
values along with an xpath check to see if a tag leaf-list contained a
tag value. I thought I read that netconf didn't support the latter at
least.

Chris.
