Subject: [PATCH] Fix schema matching when using multiple schema locations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When multiple schema locations are provided, ensure each resource
is validated against the correct schema by checking if the schema's
kind constraints match the expected resource type.

Fixes #299
