DOCBOOK: Re: XInclude vs. external entities (Re: The best way to'include' parts...)

[Norman Walsh <ndw@nwalsh.com>]

/ Janning Vygen <vygen@gmx.de> was heard to say:
| ok, you are right in this point. If i include a fiel a lots of time 
| with XInclude and ichange its location i have to change the url in 
| every href attribute of XInclude.

If I was going to use XInclude in my own system, I'd use URNs and allow
the URI resolver to get the right filename:

  <xi:include href="urn:publicid:-:Norman+Walsh:Document+My+File:EN"/>

Indirection is a good thing!

| Question: Can I use XMLCatalog with XInclude. Dont know much about 
| XMLCatalogs but i think you can do a url to filename mapping with it. 
| If xou could use it together with XInclude then you get back the 
| "level of indirection"

Exactly.

| Another important advantage of XInclude is the possibility to put 
| doctype declaration in the modular doc to validate it seperatly from 
| the main document AND you can use entites in each file which is not 
| possible within external entities. 

Yes, that's a win.

                                        Be seeing you,
                                          norm
