Check that your code validates

[shawna-slh]

We all know that it's best practice for code to validate. However, it is not a WCAG 2 requirement -- only two specific aspects are included in WCAG 2. How much of an issue is invalid markup to real-world accessibility? If not so much, then maybe do not include this tip.

As I understood it, 4.1.1 Parsing requires that code is valid and Technique G134 makes specific reference to it as well.

As I understand it, 4.1.1 is only one aspect of validated code. As I understand it, a web page could meet 4.1.1. and 4.1.2 but still have other validation errors.

valid code - G134 - is one way to meet success criterion 4.1.1. however, the requirement only applies to specific coding issues that impact assistive technologies.

Closing this issue as #118 is recommending removal of the tip anyway. If the recommendation is changed, then this issue can be revisited.

(I'm not proposing we reopen this issue) just want to add that we currently require that code validate as a general rule because when scaling up, it's less effort than evaluating and signing off on exceptions.
