Hi, let's go for the easy approach for the time being. A few things, though:
a) I still think positively of introducing namespaces to the mapping file. And yes, there will have to be some progress on e.g. <anyAttributes> first. b) Time is very limited right now (for me, at least), due to several reasons (commercial projects including). c) I am spending a lot of time making the (partial) support for JPA annotations ready to be committed. And I think it won't be long. d) And can we narrow down the types of those new attributes, e.g. use <xs:positivInteger> wherever possible or use narrower types (short instead of integer). Can I take it that whoever works on this will have to extend the JDO-specific natures for the Class-|FieldDescriptor classes ?
