Re: Other paged media processing approach - summary

Dynamic processing is well known by "old style" publishing systems like 
xyvision, app(3b2) etc.
e.g. app(3b2) provides a bunch of variables accessible during the 
rendering process.

The problem with FO is, that for every single requirement you have to 
introduce a new formatting-attribute to the standard or write an 
extension. E.g:  indentation of a paragraph, but not if it starts on top 
of a page.
If we could access those kinds variables during a FO rendering 
process,you can express you own rules, how a page should be rendered.

I know that I am not good in expressing myself, so don't be too rough with me. I might be wrong of course, but currently I don't see how my applications can be handled by any current or proposed standards except for some easy cases.)
