I'd say it's harmless if it contains more lock tokens. The server can 
figure out which one actually identifies a lock on the request resource.

Seems that we agree except for the minor point above; in practice I 
don't think that clients *will* submit multiple lock tokens in a refresh 
request, so this shouldn't be an issue.
