METS file with uppercase PHYSICAL and LOGICAL structMap

[kwon-young]

Hello,

I'm trying to parse METS file from the bnf (the French national library) and they use uppercase PHYSICAL and LOGICAL type for structMap.

This library fails to read such a file, saying no structmap were found.

I suppose the easy fix would be to modify the METS files and lowercase all PHYSICAL and LOGICAL attributes, but I was wondering if metsrw could be improved to take into account this corner case ?

Thank you for your help.
