Re: DOCBOOK: Extending using a Customization Layer

/ Todd Babinski <> was heard to say:
| expect to use this new tag is the following, and I don't want it to be
| tied to any particular location, like having to be within a section tag:
| 		<SpotId>InstallationDescription</SpotId>

You want this tag to be ubiquitous? Available anywhere that, for
example, Anchor is allowed?

Are you using the SGML or XML version of the DTD?

| does within the keywordset, but I'm trying to avoid having to do all
| that tag wrapping, and I want to add some different formatting than that
| for keywords to the output.

I don't think I understand. Could you provide a little more explanation
or a few more examples?

| 		<!ENTITY % local.spotid.class "SpotId">

This isn't really necessary.

| 		<!-- load DocBook -->
| 		<!ENTITY % DocBookDTD PUBLIC "-//OASIS//DTD DocBook V3.1//EN">
| 		%DocBookDTD;
| 
| 		<!ELEMENT SpotId - - (#PCDATA)>
| 
| 	I'm sure my attempt is just fundamentally flawed, but I cannot make
| heads or tails of this problem.  Any suggestions and help would be
| appreciated.

In short, you've created a new element, SpotId, but you haven't allowed
it anywhere. 

You might try this, as a a start:

		<!ENTITY % local.gen.char.class "|SpotId">

 		<!-- load DocBook -->
 		<!ENTITY % DocBookDTD PUBLIC "-//OASIS//DTD DocBook V3.1//EN">
 		%DocBookDTD;

 		<!ELEMENT SpotId - - (#PCDATA)>

                                        Be seeing you,
                                          norm
