Comment (by Tjoppen):
Patch looks OK, post it on the list. The way mxfenc.c is designed makes it
too easy to forget to add ULs to the primer pack. If we rewrote it
slightly to keep track of which ULs and local tags are used and don't
allow random tags to be written then we could reduce the size of the
primer pack as a nice little bonus.
I thought for a while that the primer doesn't need to contain any of the
static local tags, but S377m proved me wrong: "The Primer shall contain
all Local Tags used in Header Metadata Sets using 2-byte Local Tag
encoding the Partition in which it occurs."
