sdformat: Website schemas are old and URLs are not versioned?

[EricCousineau-TRI]

Environment

N/A

Description

• Expected behavior: Latest schemas are visible via a clearly versioned mechanism.
• Actual behavior: Current schemas are old (e.g. http://sdformat.org/schemas/root.xsd), and are not versioned. Also, all remote assets that have cross-references require remote fetching. May inline.

Steps to reproduce

Output

Per VC:

• <?xml-model?> is the mechanism used in package.xml: http://xml-model.info/
• Example usage of <?xml-model..?>: https://github.com/ros2/rcl/blob/3.1.2/rcl/package.xml#L2
• Should document that it's not necessary on SDFormat (given complexity), but can help given other tooling (e.g. editors and online linting / auto-complete)

I ran into this issue today as well. In particular, not all files are present on the schema server. At the time of this writing, the following ones are missing:

• http://sdformat.org/schemas/frame.xsd
• http://sdformat.org/schemas/pose.xsd
• http://sdformat.org/schemas/atmosphere.xsd
• http://sdformat.org/schemas/particle_emitter.xsd
• http://sdformat.org/schemas/capsule_shape.xsd
• http://sdformat.org/schemas/ellipsoid_shape.xsd
• http://sdformat.org/schemas/link_state.xsd
• http://sdformat.org/schemas/air_pressure.xsd
• http://sdformat.org/schemas/lidar.xsd
• http://sdformat.org/schemas/model_state.xsd
• http://sdformat.org/schemas/light_state.xsd
