Suggestion for XSLT 2.0

In XSLT, at the moment, if you want to check if the preceding-sibling is a
particular element type, lets say, 'heading', then the following code is
necessary:

test="preceding-sibling::*[self::heading and position() = 1]"

It seems to me that this situation (I.e testing the type of an immediately
neighbouring element) is fairly common and there should be some abbreviation
for it for preceding, following, preceding-sibling and following-sibling.
Anybody agree?, disagree?
