 When you have multiple OpenAPI files with schemas that have the same name, you can specify which file to use by including the filepath before the schema name. This is useful for multi-language documentation where you have translated versions of the same schema in different OpenAPI files.
 
+#### Example use case
+
+If you have multiple OpenAPI specifications with the same schema name but different content (such as translated descriptions), you can specify which file to use:
+
+```mdx English schema page
+---
+title: "Plant schema"
+openapi-schema: specs/en/openapi.json Plant
+---
+```
+
+```mdx German schema page  
+---
+title: "Plant schema (German)"
+openapi-schema: specs/de/openapi.json Plant
+---
+```
+
+Both pages reference a schema named `Plant`, but the English page will show the schema from `specs/en/openapi.json` while the German page will show the schema from `specs/de/openapi.json`, allowing you to display localized schema descriptions and field names.
+
 ## Webhooks
 
 Webhooks are HTTP callbacks that your API sends to notify external systems when events occur. Webhooks are supported in OpenAPI 3.1+ documents.
