 Message headers and repeating group dimensions carry a count of the number of repeating groups and a count of variable-length data fields on the wire. This supports a walk by a decoder of all the elements of a message, even when the decoder was built with an older version of a schema. As for added fixed-length fields, new repeating groups cannot be interpreted by the decoder, but it still can process the ones it knows, and it can correctly reach the end of a message.
