Subject: Re: DOCBOOK-APPS: How to select <imageobject> alternative in<mediaobject>?
The mediaobject element can contain more than one imageobject element, with the intent being to use one from the set for a given output. But there currently isn't an easy way of designating this particular imageobject for HTML output and that one for FO output. I suggested in a previous message that role="html" or role="fo" in each imageobject could be used, with a stylesheet customization to act on the role value. I'm wondering if this method would be appropriate as a standard feature of the stylesheets? That is, should the stylesheets designate the role attribute as the method to select which imageobject to use? Let me be clear that this is not a change to the DTD, but just a convention to be used with Norm's XSL stylesheets. There doesn't seem to be another available attribute that would be appropriate. And I'm guessing that any profiling would probably be done on the role attribute in mediaobject, rather than the individual imageobjects within it. But I'd like to hear what others think. Would this be useful? Is there a better way to do it?
