Confusing html5 validation warning message

[Krish1980]

What does it mean? Is there anything else that I need to rectify?

> **Notes and Potential Issues**

> The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

It means the html5 validator is experimental, nothing you can do about it. Just ignore it :)

There can’t be. The html5 spec is still a [draft](http://www.w3.org/standards/techs/html#drafts) and is unfinished. It’s perfectly safe to use however, hence why you should just ignore that warning.
