Description
The XSD/XPath regex syntax does not allow an unescaped right curly brace - it must be escaped with a backslash. Saxon does not detect this, and allows such a regular expression through. This is revealed by test case analyze-string-097, raised in response to Saxon bug #3211, which contains this error. The failure was revealed by Saxon-JS testing (Javascript rejects the preprocessed regex).
