The 3GPP specifications will sometimes omit angle brackets around multi-word names where we require them. For example, they will have <one thing : One Thing> rather than <one thing : <One Thing>>. It seems like most of the time, they will have the extra angle brackets there.

Another naming issue is that CSN.1 names are supposed to be case insensitive. We really treat them as case-sensitive, however, because we map the names to ASN.1 names, which are case-sensitive. Sometimes, you'll find capitalization differences lead to errors about missing types.
