The conversion would be needed of course - some comments are available, e.g., from here:
http://gpsinformation.net/main/epenew.txt
but as far as I know, we don't have have URA information available (except that some sources suggest URA < 10).
Btw, what's the meaning of MSVs_QCN and weight criteria? Couldn't that be used?

Another (and more clean) option would be to create extension like:
<extensions>
<ehpe unit="m">5</ehpe>
</extensions>
in analogy to what TrekBuddy does (GSM and NMEA extensions - but they also prefix it with their own namespace):

<?xml version='1.0' encoding='UTF-8' ?>
<gpx version="1.1" creator="TrekBuddy 0.9.89" xmlns="http://www.topografix.com/GPX/1/1"; xmlns:nmea="http://trekbuddy.net/2009/01/gpx/nmea"; xmlns:gsm="http://trekbuddy.net/2009/01/gpx/gsm";>
  <trk>
    <trkseg>
      <trkpt lat="45.530174693" lon="-122.614001793">
        <ele>56.5</ele>
        <time>2009-11-15T16:48:16.431Z</time>
        <fix>3d</fix>
        <sat>4</sat>
        <extensions>
          <nmea:course>314.1</nmea:course>
          <nmea:speed>22.6</nmea:speed>
          <gsm:cellid>456</gsm:cellid>
        </extensions>
      </trkpt>

Export EHPE as HDOP in gpx

Status in MobileAction i-gotU USB GPS travel logger Mac/Linux support: New

Bug description:
For exporting data from igotu to JOSM (Java OpenStreetMap Editor), it would be nice to export EHPE
as HDOP, provided HDOP is not available from igotu. I've noticed others do this as well for some
applications, e.g., EventLogger:
http://web.tiscali.it/macri/Event_Logger/Event_Logger.htm
It's more of correctness question than technical question, as the patch is actually quite simple:
