A DESCRIPTION OF THE PROBLEM :
Using SchemaFactory.addSchema with an XML Schema that has existed for years using other validation techniques returns the following error:

Caused by: org.sifinfo.sif1x.SIFException: org.xml.sax.SAXParseException: InvalidRegex: Pattern value 'UTC[-+]([0-1][0-9]|[2][0-3]):[0-5][0-9]' is not a valid regular expression. The reported error was: ''-' is an invalid character range. Write '\-'.'.
at org.sifinfo.sif1x.SIF_1_x.addXMLSchema(SIF_1_x.java:579)
at org.sifinfo.sif1x.compliance.TestHarness.createAgentTestSession(TestHarness.java:31)
... 36 more

It was [+-]. Neither works. Both are valid per W3C and shouldn't require escaping:

F.1 Character Classes

...

A single XML character is a ·character range· that identifies the set of characters containing only itself. All XML characters are valid character ranges, except as follows:

The [, ], - and \ characters are not valid character ranges;
The ^ character is only valid at the beginning of a ·positive character group· if it is part of a ·negative character group·
The - character is a valid character range only at the beginning or end of a ·positive character group·.

...

Per the last point here, both [+-] and [-+] are valid character ranges.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create an XML Schema with a similar regular expression. Load it using SchemaFactory.addSchema. Similar exception will be thrown.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
XML Schema to be parsed as with previous Java versions (that did not have SchemaFactory.addSchema).
ACTUAL -
See above.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
See above.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
See above.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Will escape - per exception, but it is not necessary per W3C spec.
