Hi group,

here are my comments on the mobileOK Basic 20070130 draft:

1.3 Claiming mobileOK conformance.

Keeping in mind that the DDC (default delivery context) specifies some 
HTTP headers to use when checking for mobileOK (see also 2.3.2), there 
is still an issue with POST parameters, which are not part of a URI.

But this is a general issue with content labelling, that could be solved 
with, guess what? HTTP-in-RDF :-)

Or are POST requests forbidden for mobile web content?
(2.3.2
> Use the HTTP GET method when making requests

2.7.3
> the action attribute of form elements whose method attribute is not
 > present or is present with value "get"
)

2.2 Testing outcomes

While in discussions about my comments previous drafts, the MWBP group 
made clear, that warnings are _no_ test outcomes, it was also said that 
they do not want to specify _which_ warning may be generated. I think in 
order for the tool developer to create a reasonable warning, it would 
help him to know at least the specific purpose why a warning has to be 
generated.


2.3.4

> style elements whose type attribute is not "text/css"

Why the _not_?


2.3.5

> images included by background-image properties in the CSS Style

What about images referenced by the list-style-image property?


2.3.6

Do the restrictions (not alternate, charset, type, media) also apply to 
xml-stylesheet PIs?


3.4

> If the Internet media type is "text/css" and the content is not
> well-formed CSS (contains mismatching brackets or illegal characters),
 > FAIL

Is 'contains mismatching brackets or illegal characters' an example for 
or a definition of well-formedness in CSS? What about conformance to the 
grammars (defined in e.g. <http://www.w3.org/TR/REC-CSS1#appendix-b> or 
<http://www.w3.org/TR/REC-CSS2/grammar.html>)?


3.7

> If image height and width are both less than 2 pixels, warn

As 2x2 images are allowed ('at most 2x2' in the prose), it should be

   If image height and width are both less than or equal to 2 pixels,
   warn
