OK. I'll leave the legal issues to others. However, since one of the
XSLT editors has shown up on this thread, can I ask about the technical
issues? Why did the WG subjected non-Java implementors to this nonsense?
There are many more widely used and implemented methods of specifying
number formatting, such as *printf.
Why so much trouble to specify one sort of output formatting? If XSLT
wanted to concern itself with low-level string representational details,
why not have a general-purpose system for the task?
If it was to provide a crutch to Java's poor string manipulation and
formatting facilities, why was this not left to extennsion writers?

How nice for Microsoft. They have the developers to spare on an
pointless exercise. Not all of us do.
