What is the purpose of UserInputSupportIndication in UserInputIndication and where are the string types used?

Through the UserInputCapability (during the capabilities exchange), an EP can signal
which string type(s) it supports for "user input". The UserInputSupportIndication in
the UserInputIndication message carries similar information, but it is not clear
for what purpose it is included in the UserInputIndication.

Furthermore, the "signal" element in the UserInputIndication can only carry an
IA5String type and the extendedAlphanumeric element can only carry strings of type
GeneralString, so what is the purpose of informing the other party about supported
string types that will never be used anyway?
