RE: Problem: XSLT, attribute value, Unicode supplement

Check that you are not using the XML parser built-in to JDK 1.6: use the
Xerces parser from Apache. The JDK 1.6 parser has some nasty bugs, and often
corrupts attribute values.

> 1.  OS X  10.6.3

> 3.  The task:  transforming an XML document into XeTeX

> The value of the attribute named correctda is here a short
