Excesive compilation time for certain schemas.yaml files

[manuelfuenmayor]

Certain documents containing schemas.yaml take excesive compilation time. No matter how short the document is.
If I remove the line :lutaml-express-index: schemas; schemas.yaml; or delete the schemas.yaml file, the problem goes away.

To replicate the issue, try to compile ISO 10303-403.
Other documents, like ISO 10303-44, also containing schema.yaml, compile just fine.

I believe this is a performance issue due to the length of the schemas. Will try it out.
