Just  a little nit. The most up to date version of the document is now on
the gcc wiki at http://gcc.gnu.org/wiki/TemplateParmsDwarf .
In that version, DW_AT_GNU_name got changed to DW_AT_GNU_template_name.

And FWIW, I agree that this should go into DWARF5.

Is there any reason why that attribute would not follow the same rules as
DW_AT_name ?

What would be the rationale for a producer to not name the pack elements ?

Thanks.
