Feature Request: Add support for APIM Schema extraction in APIOps

Summary

APIOps currently does not extract API Management Schemas (Microsoft.ApiManagement/service/schemas).
This prevents full‑fidelity environment replication and breaks parity with the APIM REST API and ARM/Bicep resource model.
I believe this has been requested for many years, but there has been no visible progress, and there is no documentation under the Limitations section regarding schema extraction.

This request is to add schema extraction + deployment support to the APIOps Extractor and Publisher

Problem

APIM schemas are first‑class ARM resources and are commonly used for:

• XML/JSON schema validation
• Reusable schema references across multiple APIs
• Legacy SOAP/WSDL transformations
• Contract‑driven integration patterns

However, APIOps does not extract or publish schemas. This results in:

• Incomplete environment backups
• Inconsistent deployments between environments
• Manual schema management outside the APIOps workflow
• Drift between APIM instances

This is a gap compared to other APIM resource types already supported by APIOps.

Requested Enhancement

1. Schema Extraction

Extract all schemas under:

/subscriptions/{sub}/resourceGroups/{rg}/providers/Microsoft.ApiManagement/service/{service}/schemas

Including:

• Schema metadata
• Schema content (XML, JSON, WSDL, XSD)
• Schema type (xml, json, wsdl, xsd)
• Associated API references (if applicable)

2. Schema Deployment

Publisher should deploy schemas before APIs that reference them.

3. Folder Structure Proposal

Suggested structure (aligned with existing APIOps conventions):

schemas/
{schemaName}/
schema.json
content.xml (or .json)

Why This Matters

• APIM schemas are required for many enterprise API governance patterns.
• Without schema extraction, APIOps cannot be used as a complete DevOps solution for APIM.
• Manual schema management introduces drift and breaks reproducibility.
• The APIM REST API already supports full schema CRUD operations, so APIOps can implement this without platform limitations.
