This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
The following tests in the Microsoft regex test set have schemas using patterns that contain octal escapes, for example \077. This is invalid in XML Schema, yet the metadata describes the tests as valid. RegexTest_141 RegexTest_151 RegexTest_155 RegexTest_517
The following tests also have schemas containing patterns in which there is a backslash followed by a digit. In some cases it apppears this is intended to represent an octal escape, in other cases it appears intended to represent a back-reference; however neither construct is legal in XML Schema regular expressions. I have not checked that all of these are described as valid in the metadata; a few of them are already marked as status="queried" for other reasons. RegexTest_141 to RegexTest_143 RegexTest_145 to RegexTest_152 RegexTest_154 to RegexTest_158 RegexTest_517 RegexTest_688 RegexTest_696 to RegexTest_707 RegexTest_836 to RegexTest_837 RegexTest_861 to RegexTest_866 RegexTest_925 to RegexTest_926 RegexTest_976 to RegexTest_977 RegexTest_1008 to RegexTest_1019 RegexTest_1172 RegexTest_1180 to RegexTest_1191 RegexTest_1308 RegexTest_1320 RegexTest_1321 RegexTest_1345 to RegexTest_1350 RegexTest_1365 RegexTest_1409 RegexTest_1410 RegexTest_1455 RegexTest_1456 RegexTest_1492 to RegexTest_1503
Also affects <test group="RegexTest_824" name="RegexTest_824"/>
Some of the tests listed above were patched as 'invalid' as a result of bug 4016
HST did check that all the listed/updated tests did contain bogus escapes
