According to export-0.9.xsd, the <model> and <format> tags follow the <text> tag. That is however quite annoying when processing the XML event stream, since it means we do not know how to process the contents of the <text> tag when we receive it. Adding <model> and <format> at the end was simply an oversight on my part when I introduced them.
Outputting these tags before the <text> tag would be simple to do, but would technically be a breaking change to the export format. I see no good way to make this backwards compatible, aside from outputting these tags twice.
As a stop gap, model and format could be included as attributes of the <text> tag. This is however rather inconsistent with the rest of the format, and would also need to be included in a new version of the XSD.
