[XML-SIG] Does 4XPath requires lex?

[Paul Prescod]

Is it really the case that 4XPath requires lex code to be compiled? And
if so, is that the case just because of the necessity to parse XPaths? I
thought that someone had done a Python-based XPath parser before. This
is a killer distribution issue, especially for Windows users. XPaths are
probably not much harder to parse than regular expressions.
