Hi,

I'm making the final fixes to my scxml interpreter. to make it compliant
with the testcase suite. Currently there is only four testcases that fail
for xpath, 241, 244, 240 and 354. (240, and 354 uses the strange
data/data/data syntax)

241 uses $var1 in namelist and of invoke and tries to match to var1 in
invoked machine. So from your comments earlier I think that 241 and 244
shall fail for Xpath?

Thanks again for you great job, and your patient replies.

/Jon
