<input type="file"> needs name=

REC-html401-19991224 says:

A successful control must be defined within a FORM element and must have a control name.

Alas, tidy 5.6 allowed me to forget that I needed a name= in

<input type="file" multiple>

causing it not to append the selected files in the browser. So at
least for type="file", do catch it when people forget a name=.

@jidanni thank you for the issue...

Although the spec you gave, REC-html401-19991224 is marked This version is outdated!, the follow on spec html401 say the same thing about Successful Controls...

And given that Tidy, in general, aims to help the user produce valid html, BUT maybe this is too big of a stretch, to ask libtidy to check for Successful Controls, within a FORM...

In constructing both a legacy 4.01 document, and a html5 document, for testing, both the legacy W3C validator, and nu validator do not appear to have such a validation check... for a missing name attribute... both docs pass...

As they do with current tidy 5.7.28...

The question is - should tidy do more in this case?

So this seems to need much more discussion... thanks...
