"Cannot find name" error

[ut-adamc]

Not really sure if this is an issue or a misunderstanding. Trying to compile an XSD that uses a type defined in another xsd, via <xs:include schemaLocation="common/typename.xsd"/>. The common subfolder and file name are present, and that is the right path (relative to the specified xsd). But I'm getting a message that it cannot be found when I run npm run makelib.
