Dear Neil,

Thank you for your comment on Easy Checks. EOWG [1] considered your suggestion.

We have taken an action item to add this to a tutorial we are developing about images. (The in-progress rough draft is at: <http://www.w3.org/WAI/EO/Drafts/app-notes/images/>; however, please do not distribute that draft URI. We plan to have it at a distributable URI within a few weeks.)

In Easy Checks, we will point to that tutorial, which will soon include information about using MathML instead of images for math equations. We decided not to add anything specifically about MathML to Easy Checks because it does not meet our criteria for easy checks (which is at <http://www.w3.org/WAI/EO/wiki/Eval_Analysis#Criteria_for_checks>).

fyi, your comment is logged at <http://www.w3.org/WAI/EO/wiki/Easy_Checks_Comments#.5Bclosed.5D_Neil_Soiffer_8_July>

We welcome additional comments on this issue or others.

Best regards,

[1] EOWG <http://www.w3.org/WAI/EO/#intro>
