for every member of the deduplicated, document-order sequence returned
by the current-group built-in function, return it if it's accessible
from the context item on the self axis and passes the node test of being
an instance of the element my-element.

>   current-group()[self::my-element]

for every member of the sequence returned by the current-group built-in
function, test if that member of the sequence is acessible from the
context item along the self axis and passes the node test of being an
instance of the element my-element.

No path operator means current-group() doesn't get deduplicated and put in
document order in the second version.  Inside for-each-group, you may
not care about that part.
