Source to xml-apis.jar version 1.0 available?

I've been tasked with determining the origin of all 3rd party source code used in our product and I've run into a problem with xml-apis.jar.   The version included in our product has a Manifest file that claims org/apache/xmlcommons/Version=1.0.  A small program which uses org.apache.xmlcommons.Version to print out the version number also reports 1.0.   The problem is that I can't find the source or binary to this version anywhere on the web, although 1.0b1 and 1.0b2 are available.  (I'm not very well versed in subversion yet, otherwise I would have checked there).

Can anyone tell me how to obtain the source to this version?  

Thanks,

Ken Ellinwood
