No, this is not handled currently by the driver. I imagine that could be 
reported as dataset metadata if that were to be implemented.

That said, you can get it if you request the 'gpx' layer with the GMLAS driver 
(which as not indicated by its name can deal with any XML data that comes with 
a XML schema)

$ ogrinfo GMLAS:out.gpx gpx

INFO: Open of `GMLAS:out.gpx'
      using driver `GMLAS' successful.
