Thinking about XML 1.1, I am wondering what will be the perceived cost/benefit ratio and if XML 1.1 will not have the XHTML syndrom. Speaking for myself as a XML user, I clearly see the cost (I need to updgrade all my XML applications to use XML 1.1 since a XML 1.0 parser will not read a XML 1.1 document and a XML 1.0 "writer" will write only XML 1.0 documents), but I don't see any use case for the XML 1.1 in my own applications (I have never met a NEL and have never needed to define names beyond what possible with XML 1.0). I guess I am not the only one in this case since I am mainly using characters from ISO-8859-1 which is already seen as quite exotic by many... Anyway, if I needed to define a migration strategy right now, with the (mis)understanding I have of XML 1.1 today, I'd classify my applications in three categories: 1) Internal XML applications which do not exchange documents with the external world. For these ones, I have no perceived need for XML 1.1 but XML 1.1 wouldn't break them either so I would be "neutral" and not force the migration but not oppose it either if the applications in my favorite distribution become XML 1.1 compliant. My workstations are running Debian unstable and would likely pick some XML 1.1 within months but my servers are running Debian stable and it's not likely that they pick XML 1.1 before the next stable release... 2) Sender applications produce XML for the outside world. Their number one priority is to produce documents that can be read by as many external applications as possible and since I have no neeed for XML 1.1 features which will balance this priority, I would firmly stick to XML 1.0 as long as XML 1.1 isn't supported and prefered by virtually all these external readers. 3) Receiver applications read documents from the outside world. They would probably the main drivers to migrate to XML 1.1: if significant information sources send information as XML 1.1, I would have implement at least a gateway to accept these documents. OTH, if the external providers which send me these documents have the same policy than I would have for my sender applications, is it likely to happen? I am an unicode illetrate and I am probably missing a lot of important reasons why I need XML 1.1 without knowing it :-) but my feeling is that if those reasons are not more clearly advertised than "IBM mainframes need it" or "it's the right way to use unicode", the adoption rate of XML 1.1 could be very low.
