[TjasaZil]

Would love to go trough the list and add missing attributes if this is needed

[Akindin]

@TjasaZil it would be awesome because now it's kinda hard to find a specific attribute without going through multiple element pages.

[estelle]

The table of attributes should be removed as incomplete both in terms of there being missing attributes (over 10 global attributes are missing from the list) and in terms of there being red non-links due to missing documentation.

Suggested fixes:

1. remove the table from this page
2. Put in a definition list limited to the attributes that have pages both in the attributes sub-tree (https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/<attribute>) and the global attributes sub-tree (https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/<attribute>). List these in alphabetical order, as currently done, but with the list of obsolete and deprecated attributes coming after a main list.
3. Add text clarifying that this is not an exhaustive list of all attributes
4. Move most of the IDL section to the IDL glossary page, shrinking the section in this page to the basics, and putting it last in terms of attribute sections.
5. Link the term "boolean" to MDN glossary term instead of the whatwg spec
6. Add a section defining "enumerated", linking to the glossary for that term
7. Add a link to the global attributes page to see also section
