[tei-council] @style /rend/rendition coexistence

[James Cummings]

I worry about some of the phrasing (which I realise are just 
shorthand discussion here). When we talk about 'overriding' and 
'processing' we have to make sure we are clear and consistent 
that this is documenting how phenomena appeared in the source, 
not how it is to be rendered in any particular output.  One may 
be taking the source text and generating a word list and want to 
exclude words which were originally in italics or red or 
something because this has a particular semantics.  I only make a 
plea that the Guidelines should be fairly agnostic about what a 
processor does with rendition documentation.  (This is entirely 
separate from what Sebastian (and others) choose to implement as 
default actions in the conversion stylesheets.)

Consistently pure,  ;-)
