FWIW:

$ wget https://www.topografix.com/GPX/1/1/gpx.xsd -P /tmp

$ xmllint --noout --schema /tmp/gpx.xsd /tmp/Ceredigion+Coast+Path.gpx
/tmp/Ceredigion+Coast+Path.gpx:13: parser error : XML declaration
allowed only at the start of the document
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
     ^

$ cat /tmp/Ceredigion+Coast+Path.gpx | tidy -xml -i -w -q >
/tmp/Ceredigion+Coast+Path_tidy.gpx

$ xmllint --noout --schema /tmp/gpx.xsd /tmp/Ceredigion+Coast+Path_tidy.gpx
/tmp/Ceredigion+Coast+Path_tidy.gpx validates


libgeo-gpx-perl cannot parse the GPX either:

$ perl -e 'use File::Slurp; use Geo::Gpx; my $xml =
read_file("/tmp/Ceredigion+Coast+Path.gpx"); my $gpx = Geo::Gpx->new(xml
=> $xml); print $gpx->version()."\n";'

XML or text declaration not at start of entity at line 13, column 0,
byte 12 at /usr/share/perl5/XML/TokeParser.pm line 353.

$ perl -e 'use File::Slurp; use Geo::Gpx; my $xml =
read_file("/tmp/Ceredigion+Coast+Path_tidy.gpx"); my $gpx =
Geo::Gpx->new(xml => $xml); print $gpx->version()."\n";'
1.1


Kind Regards,
