I tried that with the https://validator.w3.org/, also using .xhtml as
extension as it seems that it is what makes the w3c validator consider
that it is XML, with and without <?xml?>, and I get:
    Schema Error: XML document with no namespace; cannot determine any schema 
to use for validation.

Any idea on what is wrong?

Also, what could I use for offline validation?  The w3c-markup-validator
package does not seem to handle HTML5, and the vnu 
validator does not seem to be packages in debian.
