Subject: RE: [dita] Clarification Needed: Keyref on <image>
@href on image is still required by the DTDs and XSDs or has something changed in this respect since I last updated and looked at the DTDs and XSDs (way back on 11 May)? With the implementation of @keyref, @href could be optional on image, but I don't think any of the DITA 1.2 proposals called for that. Not sure if that was deliberate or if we just didn't think of it at the time. Of course @keyref existed long before DITA 1.2, so perhaps someone did think this through long ago and decided that having @href be required on image was a good idea. Having @href be required doesn't hurt anything. If @keyref is used, it just means that there will always be a fallback value to use if the key isn't defined or can't be resolved. So Eliot, are you calling for a change to the DTDs and XSDs to make @href on image optional? If not, it sounds like the Language Reference is correct as currently written. -Jeff > -----Original Message----- > From: ekimber [mailto:ekimber@reallysi.com] > Sent: Tuesday, September 15, 2009 3:58 PM > To: ekimber; dita > Subject: Re: [dita] Clarification Needed: Keyref on <image> > > In addition, the current reference entry for image says: > > " An href attribute is required on the image element..." > > But this is no longer the case in DITA 1.2, since one can specify > either > href or keyref. > > Either the attribute list is in error (href should actually be required) > or > we need to update the reference entry to indicate that one or both of > href > or keyref must be specified. > > Cheers, > > E. > > On 9/15/09 2:54 PM, "ekimber" <ekimber@reallysi.com> wrote: > > > In 1.2, the <image> element takes both the href= and keyref= > attributes. > > > > My reading/interpretation/assumption is that for <image>, href= and > keyref= > > establish the same relationship, namely from the <image> element to a > > graphic object of some sort, where the default presentation intent is > for > > the graphic to be presented with the other content of the topic (as > opposed > > to creating a link to the graphic presented in a separate > presentation > > space). > > > > In particular, I think these two image elements should be > functionally > > equivalent: > > > > 1. <image href="http://example.com/graphics/image-01.jpg"/> > > > > 2. <image keyref="image-01"/> > > > > where the effective key binding is: > > > > <keydef keys="image-01" > > href="http://example.com/graphics/image-01.jpg" > > format="jpg" > > /> > > > > Is this reading correct?
