Hi, Leif, all.

 

I agree with Leif that, for handling of multiple meta elements, 
the w3c can retroactively align its standards to practice,
by making the last meta element the one that is valid, 
in the case that multiple are specified 
(I believe that this is more in line with the w3c's  standards for style codes
anyway;  the last style declaration that applies to an element is the one that is processed;
all others are ignored, right?).

 

* * * Below is some disagreement sorry for it maybe I am wrong * * *


My two cents on having two meta-elements:  if one of these is omitted, which processes will the remaining element be used for? (This has to be specified.)

 
Also, we still have the html lang= and xml lang= elements/attributes in any case!

 

So you suggest the html and xml lang attributes plus two meta elements plus an http header?


Also, as the meta is only a fallback for when those are not specified I am not sure we need two anyway

(I need convincing; to me this is a case where aligning w3c specifications to the current practice --

using the first language specified by http or meta content-language to populate  the 
lang= attribute in the html or xml tag, as has been discussed previously --

makes sense).

 

Finally, will someone who ignores the html or xml lang =  successfully use the two meta elements? Keeping data in the right order?


My personal opinion is that they (he, she, whoever) can just as well learn to use the html / xml lang attributes as they (he, she, whoever) can learn to insert an additional meta element.

 

(I am not always for aligning w3c specifications to current practice: I still want a way to specify two document or audience languages where content is truly mixed, but not two meta elements.


The http headers and the meta elements have been the designated places for this.


I need more explanation, I guess; but I don't think I would support two meta content-language elements.  

On another note:  I do hope that someday additional meta data -- such as whether a document is a translation or an original, etc. -- will be available, however -- this has been discussed before by others.)


Thanks.

Best,
--C. E. Whitehead
