Hi,
Also, is there any real advantage to specifying as="element()"
other then readability/documentation? You've recently
discussed the advantages of doing this for non-element data
types (e.g. numeric functions). Are there similar advantages
for element()?
Yes. IMHO, the main one is early error reporting. If you
passed something else (for instance an empty sequence) then the
transform would fail, telling you why (the actual value of the
param is not as expected.) That's usually easier to investigate
from there.
