[ERR XTDE1150] It is a non-recoverable dynamic error if the effective
value of the regex attribute is a regular expression that matches a
zero-length string:
I know that, but this is about a zero-length matching subexpression. See
the expression: "(.*)*". However, XSLT already gets into trouble (well,
Saxon does) with: "(.+)*". This is not even zero-length-matching in the
substring. Is this wrong behavior?
Note: the above expression *include* the quotes.
