Annoyed. It demands a type="" attribute for the script tag, which is not required. If you're going to have an official markup schema, get it right, guys! Script tag is like the 6th most common HTML tag after html, body, head, div, and p!
I'm seeing this too. It doesn't like the source tags within the video tag nor does it like param tags within the object tag. I've selected both HTML5 and XHTML5 from the HTML Source Editing Toolbar in VS2010.
1.I've run the extension installer and restarted Visual Studio however I did not see HTML 5 in drop down list of target after I clicked Tools->Options->Text Editor->HTML->Validation. What should I do?
2.After I run the installer, is it means the CSS3.0 is in the correct location? Where is the correct location? How can I know it is worked in my VS?
The installer for this add-on does not install to the correct location. It assumes that Visual Studio is installed to the default installation location (as specified in the Visual Studio installer). However, I installed Visual Studio to a custom location. Therefore, after installation, the html_5.xsd file is in the wrong location and is not found by Visual Studio causing Intellisense not to work. Please fix your installer so that it recognizes non-default installation locations.
Thanks for this! One thing though, I'm getting this from the validator:
Validation (HTML 5): Empty elements such as 'link' must end with />.
My understanding is that's not the case. See here: http://wiki.whatwg.org/wiki/FAQ#Should_I_close_empty_elements_with_.2F.3E_or_.3E.3F
