I needed a further update as I omitted a few HTML5 attributes - e.g. itemprop, etc.
For a limited few of the attributes it will auto-complete values. For example, with the align attribute you can type just 'l' for 'left', 'r' for 'right' etc..
Note: I renamed the file as well.
The HTML completion files at my GitHub are modifications of the standard files:
Added HTML5 tags;
A few of the tags include attributes which I would consider non-optional. E.g. method, action for 'form', and width, height for canvas;
The form tag, method attribute, has auto-completion for the words 'get' and 'post' (just type 'g' or 'p');
Similarly, the type attribute for input will autocomplete - c for checkbox, d for date, etc..
Of course, if you replace the standard HTML completion files with these, it is possible they will be over-ridden by a future ST upgrade or new build.
