The HTTP_RESPONSE-11 clause on 406 status codes only applies to object elements

Entry number:
ED-1
Creation date:
20 May 2010
Section referred to:
2.4.4 HTTP Response
Description of the problem
The final HTTP_RESPONSE-11 clause, combined with the definition of the Object Element Processing Rule it refers to, could be interpreted to say that an image defined in an img element and whose retrieval returns a 406 does not trigger HTTP_RESPONSE-11. This is not the intent of the 406 exception, which only targets images defined in object elements.
Correction
The HTTP_RESPONSE-11 clause should rather read:
If the HTTP status represents failure (4xx), other than in any of the following cases: i) the HTTP status is 404, ii) the HTTP status represents a request for authentication (e.g. 401) or iii) the HTTP status is 406 for object elements (but not any other elements) when carrying out the 3.15.1 Object Element Processing Rule, FAIL

Second edition of the XHTML Basic 1.1 Recommendation

Entry number:
ED-2
Creation date:
13 December 2010
Section referred to:
3.4 CONTENT_FORMAT_SUPPORT and VALID_MARKUP
Description of the problem
The second edition of XHTML Basic 1.1 was published on 23 November 2010 and supercedes the first edition published on 29 July 2008. The W3C mobileOK Basic Tests 1.0 specification assesses validity of the document under test against the XHTML Basic 1.1 DTD, but does not clarify what this means in the context of two of more editions of that DTD.
Correction
In section 3.4 as well as in any other section where XHTML Basic 1.1 is mentioned, a reference to XHTML Basic 1.1 shall be taken to mean the latest published edition of the W3C Recommendation. In particular, the assessment of validity against the XHTML Basic 1.1 DTD shall use the DTD available at http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd. As such, the use of the lang attribute, re-introduced in the second edition is considered valid and shall not trigger the CONTENT_FORMAT_SUPPORT-6 failure message.

TABLES_LAYOUT should check td and th elements

Entry number:
ED-3
Creation date:
6 October 2011
Section referred to:
3.23 TABLES_LAYOUT
Description of the problem
The TABLES_LAYOUT test checks table cells. In HTML, table cells may be represented with th and td elements. The current wording suggests to take only td elements into account. This is not the intent of the group.
Correction
The TABLES_LAYOUT test should rather read:

For each table element:

If it contains at most one tr element, FAIL

If no tr element contains more than one td or th element, FAIL

For each nested td or th element:

If the element contains only an image (or equivalent object) whose actual dimensions are 2x2 or less, FAIL
