<extensions> tag in gpx files

I am trying to filter a gpx file that has user extensions and have found that the handling of these is inconsistent.

If I have any waypoints in the file then the <extensions xmlns:….> and </extensions> tags around the actual extension tags are dropped. This makes the resulting file bad

If I have a route with route points that have virtually the same structure then the <extensions xmlns:…> </extensions> tags are passed through.

With just a route the file is good but as soon as I include individual waypoints the output file becomes bad.

I obviously suspected the input file but can find no reason for the tags to be dropped.

I have looked in the archive for any references to this problem but so far have not found any.

Any ideas?

I attach 3 sample sets of files.

GPX 005 is a file with 2 waypoints only

GPX 001 is a file with a single route

GPX 002 is a file with a waypoint and a route

The corresponding result files have an _b added.

<extensions> are only supported in GPX 1.1 Our old writer defaults to 1.0 and generally makes a mess of 1.1 input when it writes it as 1.0. The new one does a better job of guessing when there's only a single input.

The data you provided isn't actually valid XML; it's in some multi-byte encoding.

You didn't include the commands you actually issued.

You didn't mention what version you tried, so we don't know if you're working with the old writer in 1.4.2 or the new one in the beta for 1.4.3

But even with all that, we're still going to work pretty hard to preserve, not drop <extensions> as they're part of GPX, so we may not be the tool for you anyway...
