Description Michael Kay 2006-12-31 19:19:01 UTC 
In the Microsoft regex tests, test RegexTest_178 includes a schema with the pattern

value='(foo)(\c?*)(bar)'

This is invalid because \c is followed by two quantifiers. But the metadata describes the schema as valid.
Comment 1 Michael Kay 2006-12-31 19:25:21 UTC 
A similar problem affects RegexTest_294 and RegexTest_295, which use patterns such as

value='([0-9]+?)([\w]+?)'

Similarly:

RegexTest_299 to RegexTest_317

HST checked all the patterns, confirmed that they do all have double exponents
