Cache XML Schema Validators

[George-D-S]

At present each XML Validation request seems to involve building an LXM Validator from scratch.

This will be quite a costly operation.

The AI Overlord suggests either pre-loading them as part of the FastAPI Startup process, or just using the standard LRU cache with a "get_validator("1.2.3")" type function.

I wonder if this might also apply to the current RDA Converter?

It would although we turned off the schema validation step.
