Why would UAS1 send any provisional response (other than a 100 Trying) 
before figuring out there was an error?  I've never seen an 
implementation do this, and the spec is pretty clear that you 
immediately send these error before you get the the processing stage 
where you would normally send a 18x.

are you asking this in general, or only after the UAS sent its own 
to-tag?
