Old is pre Oct 1999.

all axes are affected the same way, not just children and
ancestor so the most common things to fix are

from-plural(stuff)   to singular::stuff
qname ()                name()
expr attribute          select
param-variable          param
param                   with-param

But as others have commented, appendices of the xslt and
xpath drafts give a more full account. (Make sure you do
those last two transformations in the correct order, last
time I forgot and changed param-variable to param first,
which wasn't a brilliant plan:-)
