[PRL] AOP questions

[Karl Lieberherr]

My view of AOSD is as a technology for incremental development of
artifacts. You have built an artifact using a dominant structure, with
an evolution path in mind, and now you want to add a new concern. Most
likely, adding the new concern will cut across the dominant structure
and AOSD studies coordinate systems and advice mechanism for expressing
where to add the new concern.

You can apply this to relational structures in math., e.g., graphs or
grammars or XML, and of course programs.
