HTML5 on Eclipse PDT

I'm new to Eclipse, using PDT (helios). I keep getting warnings for "Unknown Tag (article)", also besides 'article' theres unknown tag warnings with 'nav', 'footer', 'header', etc. What I can infer from this is that Eclipse has a problem with HTML5 Validation.

I have one file Template.php which is used throughout the project and I've defined the DOCTYPE like so:

<!DOCTYPE html>

I tried looking into Project>Properties>Validation But I don't see anything there that I can change / modify for this. How would I ensure HTML5 is properly validated by eclipse?

How about try using Aptana Studio's HTML editor which seems to be able to understand HTML5? – Mikko Ohtamaa
Which version are you using? Are you sure it's supposed to support HTML5? – nitind

@aaamos that question is from 18 months ago. Since then the HTML5 support was supposed to have been default. – dartarrow
True, but then, so is Helios. See answer below. – Amos M. Carpenter

According to this blog post, HTML5 support was added to Eclipse Helios after its initial release. Have you made sure you've updated to the most recent version? If not, consider going straight to Indigo - since Eclipse doesn't require installation (just unzip and run), you can use multiple versions at the same time.
