Don't think so; that's just the standard static mapping. Bob pointed me
to this:

which seems to be the right thing (you can just input garbage into the
form to download the PDF). It is a mechanism where the AP and client can
request of each other to apply certain DSCP markings (and thus WiFi WMM
classes) to certain flows. The document has gems like:

So yeah, that'll all end well...

Also, what is it with people wanting to provide AR in sports stadiums?
Crops up in all these "future of wireless" type marketing presos...
