Attributes are usually easier to share than functions and algorithms. That's why I suggest using "data dictionaries" nearby. Most common CRUD idioms are readily attribute-able such that we don't need Turing Complete sub-languages for majority of them. We just need useful code "hooks" to customize when needed, which is the usual bottleneck of attribute-driven development.
