RE: [aspectj-users] OT: Crosscutting concerns and XML

[Russell Miles <russellmiles@xxxxxxx>]

No worries :-) Sorry if I sounded aggressive, really wasn't my intention.

Yeah, I'm basically looking at some of the decisions being made in various XML based standards in my field and coming across what I perceive to be crosscutting concerns that are being interspersed with the core structure for which the standard is being written. For example, XML to describe a sensor is being made incredibly complicated by including capabilities to present different language types on a per element basis, where internationalization - particularly on such a per element basis - seems a good candidate for a crosscutting policy. So I started to think around ways to make this sort of solution more moudlarized, hence the posting.

I am really looking at crosscutting concerns right in the XML itself, not necessarily anything to do with how it is parsed. Just a means to elicit and effectively describe the crosscutting definitions, probably in the XML schema really, rather than the mishmash of core structure and crosscutting concern that appears to occur in some of the schemas I come across. XML schema nicely supports inheritance and specialization etc. But nothing I can see for crosscutting...

Cheers,

Russ
