What is the difference between 0x9211 and 0xa211? Ok, I saw 0xa211 is not writeable. Is there a reason why the 2nd tag is not writeable?

A number of tags between 0x92XX and 0xa2XX have changed
their tag ID's at some point in time.  Rather than give these different
tag names to allow them to be differentiated, I have left the tag
names the same and only made one of them writable.  The
one I have made writable is the one I have found to be the
more common of the two, although in general these tags are
not very commonly used to begin with.

Please change the names, as already mentioned in my other posting, I have problems. It would be very nice, if I could test it in a preversion. If this doens't work for me I can't go on with my bash script.

I hesitate to change tag names for reasons of backward compatibility.
Instead, you can easily override the existing definitions by adding
a user-defined tag with whatever name you want.
