Hello WCAG-WG,

SC 4.1.1 requires limited validity checks for markup: unique ID values, proper tag nesting and closing and a check for duplicate attributes.

However, the WCAG 2 Understanding documentat suggests that conformance  claim could include something along the lines of:
"The documented set of accessibility-supported content technologies relied upon for this claim includes XHTML 1.0 (Transitional), CSS 2  and  JavaScript 1.2. "
Refer: example conformance claims on  http://www.w3.org/TR/UNDERSTANDING-WCAG20/conformance.html#uc-conformance-requirements-head
Does this imply that one can make such a statement only after ensuring that markup / CSS / JS code is valid?
Please clarify whether validating the code for CSS / JS / XHTML beyond what is suggested in SC 4.1.1 is  required for a conformance claim if for instance, all three technologies are used.
