I'd like to thank Lou again for the rewrite of the draft section for TD that I'd done in the processing-model branch -- it is a substantial rewrite. This is at http://teic.github.io/TEI/TD.html#TDPM or if you prefer the xml https://github.com/TEIC/TEI/blob/lb42-procmod/P5/Source/Guidelines/en/TD-Doc... I've given the chapter a quick skim read and my initial suggestions/thoughts are: "22.4.4.4 Processing Models" Should processing models section be a new 22.4.5? It is longer an more substantial than some of its siblings at this level. " In the present implementation, rendition is expressed using the W3C Cascading Stylesheet Language (CSS)" In which implementation? This may be confusing, perhaps just the second half of that sentence? "The intent is that these should be presented in an italic font as inline elements:" maybe: "The intent is that these elements should be presented inline in an italic font" (i.e. They may not be being processed into 'elements', that may be mistaken as suggesting this is only for HTML output or something.) You are right that at the bottom of the Output Rendition section we could say something about 'Why CSS', but this is for the same reason that we suggest elsewhere inside the <rendition> element as a formally declared stylesheet language. This might suggest that we should be having a @scheme attribute like <rendition> with css as a value? In Implementation: "If the useSourceRendition attribute on the model has the value false then any rendition attribute on the source element can be ignored; otherwise its value must be combined with that given in the outputRendition element, if any." Maybe reverse this since it might contradict what was said above in the bit on useSourceRendition? So: "If the @useSourceRendition attribute on the model has the value true then any rendition attribute in the source element must be combined with any given in the outputRendition element, otherwise all rendition attributes in the source should be ignored." -James -- Dr James Cummings, James.Cummings@it.ox.ac.uk Academic IT Services, University of Oxford "
