Indeed this works. I also overlooked the textops' selects.

`@hf_value.path.uri' works as well (collecting all uri's in 'Path' HFs),
but not the version with star. Which is strange, considering that this
`*' example also appears in textops doc, but (again) the 'select_param'
non-terminal definition in cfg.y seems to clearly disagree with this
syntax. Are you using the notation as a shortcut, or is it there really
a discrepancy?

But speaking of select syntax and Path extension, the first Path value
might have to be used by a registrar proxy for routing upstream;
optimally, it might need special treatment, like detaching it from the
group (to avoid storing it twice). So, there might be the need of only
select addressing a subset (just like [1:] in python's [a:b] notation).
