Validate Dataverse customization XML

Run the schema validator after editing Dataverse customization XML, and always in contexts where the live LSP does not push diagnostics (subagents, headless, CI):

pwsh "${CLAUDE_PLUGIN_ROOT}/scripts/Validate-DataverseXml.ps1" <file-or-dir> [more paths / globs]

Non-zero exit = validation failed. It picks the schema by the file's root element and fails loud on unknown roots.

When to run it

• Headless / subagent / CI edits — the lemminx LSP only pushes diagnostics in the main interactive session; elsewhere you get nothing unless you run this.
• Forms, charts, viewers, and parameter XML — the LSP does not cover these live; the validator owns them, and a PostToolUse hook auto-runs it on them after an edit.
• Before pac solution pack / import — a final gate so bad edits fail here, not at import.

How to read the output

Whole-form FormXml and whole-file Customizations.xml validation is indicative, not authoritative: the bundled 9.0.0.2090 schema lags modern attributes, so it reports false "not declared" errors on out-of-the-box content. Confirm YOUR edit is clean by checking that no error references your own element/attribute names (grep the output for them); treat pre-existing OOB noise as expected. The ribbon fragment (RibbonCore.xsd) is authoritative.
