Currently protocol parameters are just exposed in Tp-Qt4 in ConnectionManager::ProtocolParameter::name(), Account::parameters(), AccountManager::createAccount() identified by their bare name as a string. We should probably provide constants for well-known protocol parameters (at least the most common mandatory ones) and document their semantics in the documentation for the constants. Then again, there probably won't be too many account editing UIs, and when writing them one should have CM-specific knowledge anyway, so not sure if this is very beneficial.
Nah, decided that protocol-specific UIs are wanted in any case, so it doesn't help much to have a few generic parameters described / accessors provided for.
