Bug ID: 29855
Summary: [FO31] Non-capturing subexpressions
Product: XPath / XQuery / XSLT
Version: Candidate Recommendation
Hardware: PC
OS: All
Status: NEW
Severity: minor
Priority: P2
Component: Functions and Operators 3.1
Assignee: mike@saxonica.com
Reporter: mike@saxonica.com
QA Contact: public-qt-comments@w3.org
Target Milestone: ---
The F+O spec states in 5.6.1:
The presence of the optional ?: has no effect on the set of strings that match
the regular expression
This is not strictly true. In the presence of back-references it can index
change the set of strings that match the regex.
I am fixing this by adding "In the absence of back-references (see below), " to
the start of the sentence.
