The parser doesn't like the second 'aixm:extension' field. If I
comment it out, as:
<!-- aixm:extension>
<aimsua:AirspaceExtension
gml:id="Airspace01_TS1_SUA_EXT">
<aimsua:suaType>MOA</aimsua:suaType>
</aimsua:AirspaceExtension>
</aixm:extension -->
The document parses. If this is an error in the sample
file, I'll bring it up with the authors of that file.
