Hi list,
My input dataset has 69 lines, but when I display it with Firefox
(1.0.7, win2000pro),
it shows me only the first 57 lines (no error msg). It works fine with
SAXON 6.5.4
however. It seems to me to be a storage restriction in connection with
the recursion
occurring to process nested lists (ul). But what can be limited to
less than 5k ?
What can I do to improve my stylesheet?
