![Re: Universality [Re: What is a namespace ... really?]](/images/get_stylus.gif) ? Where the original note says: > What if I want to create a schema specifying that (for my set of > documents) an html:p element may contain a tei:foreign element, or a > docbook:Trademark element in addition to the regular HTML elements? > > What if I want to create a schema specifying that (for my set of > documents) an html:p element may *not* contain an html:font element? > > It doesn't make sense to have to create a new and different namespace > for either of these -- I'm still using the individual elements in > mostly the same way. is the reader to understand that both "peculiarities" would hold at once? hold "universally" in a given processing environment? that is, it's not a matter of wishing to present two documents, each with with a different specification for <html>:p . david@m... wrote: > > james anderson writes: > > > In particular, I would presume that the "html" in mr megginson's > > note is literally a prefix term and that the reference is to the > > qualified and not the universal name. > > Not at all -- I used the "html:p" simply as shorthand for something > like > > http://www.w3.org/Profiles/voyager-strict + p > > (By the way, I'd like to note that I strongly dislike the idea of > having three separate HTML namespaces as proposed in the Voyager spec > [1]; after all, an HTML <a> is an HTML <a> is an HTML <a>, whether > you're using the loose, strict, or frameset version of HTML). > But, ... as soon as the content model changes - as would appear to be the case from the variations, for example, in the respective %block entities, then the respective schemas describe respective elements which do not meet the class/type conformity requirement set out below.
