Re: [questionnaire] Addendum to Mobile Web Best Practices ready for publication?

To: Mobile Web Best Practices Working Group WG <public-bpwg@w3.org>
Thanks to Kai for working on this document. And apologies from me for 
not having contributed for several months.

Here are a few suggestions:


* Mark up the table of contents as a real UL list (without the BR line 

* The section for each BP "Relevant device properties" needs some 
explanation. I understand that this means properties that can be 
detected on the server. This is covered in the BP document under "3.5 
Establishing Context" [4].

* I think that references should be marked in the text 
[REFERENCE_HANDLE] with a link to the  section at the end of the page.

+1.1 Purpose

* "Mobile Web Best Practices contains sections against each best 
practice" might be better written as "Each of the Mobile Web Best 
Practices contains a section called "What to Test".

* The preceding isn't really about the purpose of the document, but I 
can't see where else it fits in.

* Missing space in "evaluationsin".

+1.2 Relationship to mobileOK Basic Tests

* The second paragraph ("Many of the tests described in mobileOK Basic 
Tests are...") is useful, and is an addendum to MWBP, but I don't think 
it belongs in this section as many of the tests described in this 
document are not useful when determining suitability of content for use 
on more advanced devices either. It's more a general comment on MWBP as 
a whole.

* "completes the set of Best Practices" perhaps better as "completes the 
set of tests for the Best Practices"

+2.1 Evaluation Scope

It might be useful to cite the Web content Accessibility Guidelines (now 
a W3C Recommendation), the section about conformance that has two 
clauses "Full pages" and "Complete processes." These are not specific to 
accessibility and apply equally well to MWBP. So we should mention them 
I think. In fact, just below it the item "A concise description of the 
Web pages" is also relevant.

+3.4 Background Image readability

The Example should perhaps be an image (remembering 
STYLE_SHEETS_SUPPORT). Without CSS it is black on white.

The WCAG 2.0 Techniques [2] give a list of tools to check this, 
including one developed especially for WCAG 2.0.  I think that the 
Ishihara Test for Color Blindness isn't very useful as it consists of 
very specific examples. If people aren't using exactly those colours it 
won't help them.

WCAG success criterion 1.4.3 Contrast (Minimum) [3] gives a definition, 
and exceptions to this which might be worth mentioning.

+3.5 Balance

Under "Relevant device properties: Support for non-linear navigation 
across links" I didn't understand this until I read the rest of the 
section. Perhaps "non-sequential" or "skipping/jumping links" might be 

That's it for today,
