Subject: Re: [dita-comment] Possible improvement for DITA 2.0

Hi Radu,

According to the 1.3 specification, when key references are resolved on an image, text in the key definition that would normally become link text should be treated as the alternate text.


The relevant text is here:
> For empty <image> elements, effective content is used as alternate text, equivalent to creating an <alt> sub-element to hold that content.

Speaking on behalf of the DITA-OT team, I'm pretty sure that is not working properly right now, and should be treated as a bug in the processor. I'm not sure if other processors handle this condition.

When properly implemented, I believe this would address the issue you're seeing; updating your sample key definition, the following would result in the proper alternate text:
>   <keydef keys="myImage" href="">>     <topicmeta>
>       <linktext>Alternate text</linktext>
>     </topicmeta>
>   </keydef>

One of our users uses in topics DITA <image> elements with @keyref in
order to be able to switch between different target images.
But she also needs to set alternate text for each image. And when
changing the @keyref on the image she also wants the alternate text to
change based on the new target image.
How about if we allow defining the <alt> element in the <topicmeta>:

>   <keydef keys="myImage" href="">>     <topicmeta>
>       <alt>Alternate text</alt>
>     </topicmeta>
>   </keydef>

so that when an image has a @keyref pointing to the definition, the
<alt> element can be inherited from there if not directly specified
inside the <image>?
