Yeah, no. I didn't look very carefully at that. This is what a header
from an actual gpx file exported from humminbirdPC looks like:

<?xml version="1.0"?>
<gpx xmlns="http://www.topografix.com/GPX/1/1"
     creator="HumminbirdPC Version 2.5.8" version="1.1"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:h="http://humminbird.com"
     xsi:schemaLocation="http://www.topografix.com/GPX/1/1

So no, it does appear to be 1.1. I don't have any older versions of
humminbirdPC to
compare with, so AFAIK, this is the way it is. I'll update that.
Also, I don't have the
  <extensions>
    <h:version>1.0</h:version>
  </extensions>
bit in my header either, I'll add that too. Unfortunately, there's no
place (that I've found) that has the xsd for this, eg like Garmin's
http://www8.garmin.com/xmlschemas/GpxExtensions/v3/GpxExtensionsv3.xsd

Actaully, using any of the web-based validators I've found, none of my
files validate. It appears the <extensions> section must be at the end
of the enclosing tags. Weird.

ie

<wpt lat="30.000000436" lon="29.999998503">
  <ele>0.000000</ele>
  <time>2008-08-14T22:03:10Z</time>
  <name>030-030</name>
  <cmt>030-030</cmt>
  <desc>030-030</desc>
  <sym>Normal</sym>
  <extensions>
    <h:depth>3000.000000</h:depth>
  </extensions>
</wpt>

is ok. but

<wpt lat="40.000003601" lon="40.000000998">
  <ele>0.000000</ele>
  <extensions>
    <h:depth>4000.000000</h:depth>
  </extensions>
  <time>1970-01-01T00:00:01Z</time>
  <name>040-040</name>
  <cmt>040-040</cmt>
  <desc>040-040</desc>
  <sym>Normal</sym>
</wpt>

is bad.

Will look at it  tomorrow.
