Where might one find FIX 5.0 SP2 example messages?
Probably best to search the internet for publicly available interface specs (aka Rules of Engagement) of electronic execution venues. There may also be examples in specific FIX Extension Packs. Are you interested in the usage of certain FIX messages, fields and valid values that were unavailable prior to FIX 5.0 SP2 or is the question about a specific syntax (encoding), e.g. tag=value or FIXML?
Actually, I was wanting to see a few example messages in the context of using a FIXT.1.1 session. Just wanted to get a feeling of the two in concert.
If your focus is the session layer (FIXT) then I suggest to look at the test cases in the related spec (http://www.fixtradingcommunity.org/pg/structure/tech-specs/transport-layers-for-fix). The version of FIX (5.0 SP2 or lower) does not really matter as the message flow paradigms have not changed with the introduction of FIXT. The main change was transport independence, i.e. changing/adding fields in the message header to allow a single session to transport FIX messages from different versions.
