Mozilla XSLT Error codes

So I'm going crazy working with XSLTprocessor under mozilla.   The
error codes returned from catching an exception are understandably
cryptic (0x80040005 for example), and I've deciphered a few, like
600001 is malformed XML, and there are 4-5 others i recognize, but I
just got one 0x80060018, and realized how nice it would be to have an
error code-> error description, rather than cutting code out till the
error goes away.   Does such a list exist?


Thanks
