If you mean that's why you think they should be the same, i can't argue
with that. But that isn't why they _are_ the same. the default priority
assignment never looks that closely, any predicate has the same effect.
consider foo and foo[true()]  for instance.
xslt2 of course has several other overlapping node tests besides * and
node() for example element() schema-element() etc.

Best to view the default priority as a convenience that avoids
mentioning priorities in the overwhelmingly common case of a template
matching * and a bunch of templates matching specific element names.
If you need anything subtle, put explicit priorities on (and choose a
big number like 1000:-)
