And probably very obscure and rare requirement. In almost all DocBook 
customizations for my clients I have support for specifying linebreak 
and pagebreak using PI. Such instructions are sometimes necessary to 
fine tune printed output, but still they are very rarely used. I'm not 
asking for adding them to DocBook markup, because this can be considered 
as a promotion of their usage, which is bad thing and I do not want to 
do it.

Ability to specify different steps for linenumbering in document is also 
bad thing, because it gives too much freedom to author and result will 
be not consistent, which means that it will look more or less ugly (or 
at least strange) and will confuse readers. Once you have some general 
(and possibly very complex rules) for this behaviour in stylesheets, you 
are producing consistent output. If you need different numbering 
behaviour for two programlistings in 500 page programming textbook, then 
you should utilize custom attribute or PI for it. If you need dozen 
different numbering schemes in your document, then you are probably 
doing something wrong.
