You can wrap a sequence object around anything; it's only useful for packaging things up as an alternative to sosofo-append, and for specifying inherited characteristics without specifying a flow class. It just happens that the latter is useful for specifying font-size:, etc. when you have a sequence (non-technical usage) of character objects. You can even wrap a sequence around a simple-page-sequence and, in fact, as I recall Jade always does so in order to implement the declare-initial-value primitive. A paragraph object accepts any kind of object in general. Whether the backend will do anything useful with it is another question. For example, aside from just characters, you could flow a paragraph into a paragraph. Since a paragraph is supposed to format display objects which become children by prefixing them with a break, this will actually produce what appear to be (at least) two paragraphs. What things besides characters can you flow into a paragraph without introducing a break? Any inline object. For example, a line-field; an external-graphic with display?: #f; in general, even a display object, provided you wrap it with an included-container-area with display?: #f. --FC DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
