Context in nested loop

I am unclear with the correct syntax for the corresponding context of the
$name and $attr
variables in the following repro. For $name, mailto:../@name is what I want,
but I know that is
incorrect and for $attr, "." gets the value and not the name. This is similar
to a question I
had a few days ago, yet in this case I am still unable to figure it out. Does
a way exist to avoid
the variables?

Thanks,
