As much as I wanted this to work, there is one blocker in an index and index-has-key that has limitations to this approach. Additionally, there are some problems with map processing that could prove a viable successor to "Approach #2" in #1002 where we look up statement index information around required attachments with props in the respective catalog/profiles. That, and we need string-join() for some of those relevant operations, which means this approach is effectively blocked by the following issues.

• Casting error during validation with dynamically compiled modules metaschema-framework/metaschema-java#297
• string-join & contains metaschema-framework/metaschema-java#298
