   Do other implementations do the same, if yes too bad, work around
it, if no and EXSLT doesn't mandate that behaviour, feel free to fix :-)

I tried to check Saxon and Xalan, but they don't seem to support str:split. But I had a look at the implementations in plain XSLT on the EXSLT website:

They both remove empty tokens intentionally. So we should keep the current behavior.

The fn:tokenize function in XPath 2.0 keeps empty tokens btw:

"Zero-length strings will also occur in the result sequence if a separator occurs at the end of the $input string, or if two adjacent substrings match the supplied $pattern."
