Issue with TCX files being invalid

[Logiqx]

Just like GPX, the TCX format has associated schemas / XSD files. All applications generating TCX files should ensure they generate valid TCX files.

I tweaked the header of a TCX file generated by the COROS app to attempt validating it using freeformatter.com but a number of errors are present.

The COROS developers should look to resolve these issues, much in the same way as I documented for the GPX export.

See summary of GPX validation issues for some pointers:
