Show SimpleData in Properties

[jidanni]

I made a .KMZ with

ogr2ogr chtpoor.kmz chtpoor.csv -f LIBKML -oo X_POSSIBLE_NAMES=lon -oo Y_POSSIBLE_NAMES=lat

that looked like

    <Placemark id="chtpoor.3">
      <ExtendedData>
        <SchemaData schemaUrl="#chtpoor.schema">
          <SimpleData name="mcc">466</SimpleData>
          <SimpleData name="mnc">92</SimpleData>
          <SimpleData name="lac">24600</SimpleData>

but in Viking there was no way to see that any of that even existed when clicking on a node and checking Properties.

OK, I'll try GPX instead of KMZ.

ogr2ogr chtpoor.gpx chtpoor.csv -oo X_POSSIBLE_NAMES=lon -oo Y_POSSIBLE_NAMES=lat -dsco GPX_USE_EXTENSIONS=YES

<wpt lat="24.19219" lon="120.855395">
  <extensions>
    <ogr:mcc>466</ogr:mcc>
    <ogr:mnc>92</ogr:mnc>
    <ogr:lac>24600</ogr:lac>

Still no way to see any of that in Properties of a given waypoint.

No, clicking GPX extensions in the image #246 (comment) doesn't show them either.

Usage case:
Clicking on a cell tower to see its details (without using the balloon method.)
