Hi,
Our application generates a FIXML message which would be later converted into a FIX message by another application. In the process, we found three tags in FIX4.4 but missing corresonding elements in FIXML. Any help would be appreciated.

NoXXX fields are not needed when you use FIXML syntax instead of tag=value where it is needed for proper parsing. This is indicated in FIXimate with “(not used in FIXML)” in the XML name column. Please refer to the FIX Specification Volume 1, FIXML syntax. With FIX 4.4 Errata, the DTD Schema was supplemented by an XML Schema version which is probably the one you are using. The FIX 5.0 SP2 Errata Specification is the best source to learn about FIXML design rules, starting on page 29. Repeating groups are implemented as XML elements. The cardinality of a repeating group is not explicitly provided but result from the number of instances of the same element, e.g.



is the result of the conversion from the following tag=value “representation” (not the wire format but a logical view):
453 NoPartyIDs=3

448 PartyID=“OCC”
447 PartyIDSource=“D”
452 PartyRole=21
448 PartyID=“99999”
447 PartyIDSource=“D”
452 PartyRole=4
448 PartyID=“C”
447 PartyIDSource=“D”
452 PartyRole=38
