If there are local elements / types which refer to externally defined elements / types (e.g. GeologicUnitPart, defined in geologicUnit.xsd, extends gml:AbstractObject, which is defined in some GML schema, don't remember which one), then the parser already imports the external schemas automatically: if I remove the check on the importing schema's content and always force the import, I'll be doing the same job twice, possibly ending up with multiple copies of the same element / type definitions (maybe this is not true, didn't test it). Importing and parsing remote schemas can be a time consuming task: I have a unit test which loads all GeoSciML 3.2 schemas plus their dependencies (GML 3.2, GMD, ecc...) and it takes more than 1 minute to run, so I would strive to avoid importing the same schemas twice. It is true that app-schema caches remote schemas locally, so the second import would be much faster, but the fix I wrote is in the gt-xsd-core module, which is likely used in other contexts, where caching may not be available. Perhaps I should apply the fix to the app-schema extension only? -- Best regards, Stefano Costa == GeoServer Professional Services from the experts!
