Subject: Re: [dita] Missing Paras on Attribute Specialization
This approach seems prudent, Eliot. The greater concern is probably
whether this portends other places that should be reinspected. Other
than that, this looks like an editorial catch to me. On 9/21/2010 6:35 AM, Eliot Kimber wrote: Robert discovered that I had missed out a few paragraphs on attribute specialization in the reorganization of the general discussion of specialization. The original content was: -------- Specialization of attributes When creating a structural specialization, you can limit the contents of existing attributes on your new elements; you can also create new attributes through domain specialization based off of the props attribute (for conditional processing) or the base attribute (for other simple token attributes). Domain attribute specialization allows DITA document type developers to incorporate new conditional processing attributes that can be used for filtering and flagging, or new attributes with no existing equivalent that can be managed and generalized in the same way as conditional processing attributes. The new attributes need to be based off of either props or base: * Attributes specialized from props are identified as conditional processing attributesAttributes specialized from base have no existing behavior associated with them * Values in specialized attributes should be preserved during generalization and respecialization * While generalized, the attribute values should still be understandable by both general and specialized behaviors, and be treated as equivalent to their specialized form. * For example, conditional filtering should work the same way on specialized attributes and on generalized attributes. Because there is a strong possibility that the existing conditional processing attributes (audience, platform, product, and otherprops) will be moved into a domain based off of props in the future, structural specializations are discouraged from limiting the values in those attributes. -------- I think the appropriate action is to add this content, more or less as is, as another <section> within topic 2.1.4.3 Specialization, where it would be parallel with the other sections. This content doesn't add or remove any existing normative statements about attribute specialization so I don't think there's any functional implication to adding it. I would just need to make sure I don't add any redundant statements. I will take this action if there is no objection from the TC. Cheers, Eliot --
