Official Twitter follow button code does not pass validator
I ran my website through Validator and it returned two errors, both of which relating to the official Twitter follow button code.
The code for the larger button is:
Validator returned these errors when checking my site as XHTML 1.0 Transitional:
there is no attribute "data-show-count"
there is no attribute "data-size"
So what is the deal here? Obviously these two attributes exists. Removing the data-size will return the smaller version of the button.
It should work with HTML5 Doctype.
