The first two are probably issues with the parsing. Instead of making it easier, the FPL has made it much more difficult to create a data dictionary. Back in FIX.4.2 the entire spec was available in one html file. Not ideal but relatively easy to parse. In the past two releases however they have only released the spec as 7 Word documents. This makes parsing difficult, particularly since these documents are seemingly created by hand and there isn't perfect consistency in how things are laid out. We tried to account for all of the exceptions, but some slip by. So we just try to fix them as they are reported. As for the LinesOfText, well, Fiximate lists it as NoLinesOfText, while the official FIX 4.4 specification document lists it as LinesOfText. Since the document is supposed to define the standard, that's what we go with (even through NoLinesOfText is what it really should be if you go by the naming convention). A bit worrisome since it appears someone is keeping two versions of the spec. I think it is likely due to a transition the FPL is going through. I'm told that the spec is now being kept in an Access database, so hopefully future versions will be generated off of this database. --oren On Aug 29, 2004, at 3:36 PM, James Wiggs wrote: > QuickFIX Documentation: > http://www.quickfixengine.org/quickfix/doc/html/index.html > QuickFIX FAQ: > http://www.quickfixengine.org/wikifix/index.php?QuickFixFAQ > QuickFIX Support: http://www.quickfixengine.org/services.html > > > Folks, > > I'm working with the FIX44.xml specification document off the > QuickFIX site and I've spotted what seem like discrepancies between > it and the FIX4.4 spec at fixprotocol.org.
