Hi Carlos, Like Matthias, I discovered later that it is part of the spec. In fact, the spec only contains two small paragraphs about this topic. regards Didier PH Martin mailto:martind@xxxxxxxxxxxxx http://www.netfolder.com -----Original Message----- From: owner-dssslist@xxxxxxxxxxxxxxxx [mailto:owner-dssslist@xxxxxxxxxxxxxxxx]On Behalf Of Carlos Villegas Sent: Monday, July 05, 1999 11:21 PM To: dssslist@xxxxxxxxxxxxxxxx Subject: Re: Unregistered flow objects Didier Martin wrote: > Actually, with this kind of expansion mechanism (the > declare-flow-object-class ) you can add new flow objects to the core set and > have them switched on or off by a declaration.

What it is not standard, of course, is the particular extension flow objects added by Jade, and how that is actually done in the implementation. The declaration is standard, but of course, the backend that implements those extensions needs to know about the new objects and so they need to be defined in some internal structure inside jade. The same applies for additional characteristics, see section 12.4.6 declare-characteristic, as are the ones added to the simple-page-sequence by the RTF and TeX backends (page-n-columns, etc.).
