Adrian made the suggestion some time ago of using the fo:declarations element to override configuration on a per-document basis:
It’s not as fine-grained as a PI (no means to say “from now on, do this”), but I share Jeremias’ feeling about PIs.
From my experience, a mechanism saying “from now on, do this” is likely to confuse a non-trivial amount of users. I think there should be the following hierarchy (which is already complex enough) - config file - overridden by command line arguments - overridden on a per document basis by extension elements in the fo:declarations section - overridden on a per element basis by extension attributes on the element - overridden by specific "force" command line arguments ("force all warnings/problems to be fatal" may be the only one of this kind) J.PIetschmann
