lccn casing

[eroux]

Most of the time the lccn data needs to be upper cased (hence a normalization in that direction in xmltold), but sometimes it doesn't... for instance

• BQ7815 .K86 1990z should have a final lower case z
• BQ960.O737 D34 199u should have a final lower case u

The format of LCC call numbers (note these are distinct form LCCN's) doesn't mention lower case letters. I was able to find an example LCC call number that has a lower case letter in the Cutter number: PZ7.J684 Wj 1982 but the rules are rather involved.

We could upcase the LCC call number up to the year which involves a bit of parsing which would mess up the example above but the search by numbers is case insensitive so perhaps it doesn't matter too much if some lower case letters are erroneously up cased.

I think the lead to automatically sync them is probably our best shot, we just need to find a contact
