(IE; it has implied > semantics to the "code"). all along, I take care to avoid using such terms "<xhtml:b> has meaning" because, as I was saying in a previous post, "semantic is used for terms that means something" I argue that "my name is <xhtml:b>Philippe Poulard</xhtml:b>" has the same meaning that "my name is Philippe Poulard" to be coherent, I won't say that "<xhtml:b> means bold", I will say that "<xhtml:b> just stands for bold", because <xhtml:b> carries no meaning to its text data the semantic applies on the content, not on the container : <author> can't be an author, it can only contain a text that corresponds to a person name that is (should be) an author > > <snip> > >>>Respectfully disagree: structure and semantics are in the eye of the >>>beholder: tell me is a blob of XML stored in a RDB structured or not? >>>Does the same blob have any semantic meaning?
