This issue is not new, however was raised in the OSGeo Standards mailing list as a result of the pycsw Incubation process

Problem Statement

FOSS4G software may encounter distribution issues when including OGC Schemas as part of the codebase.

Use of OGC XML Schemas in FOSS4G Implementations

• used to re-publish schemas:
  • XML responses cite xsi:schemaLocation of pointing to locally cached OGC schemas
    • e.g. xsi:schemaLocation="http://www.opengis.net/cat/csw/2.0.2 http://HOST/csw/2.0.2/CSW-discovery.xsd">
• used within software to perform XML schema validity of XML based HTTP requests
• others?
