[FEATURE] METS application profile validation

[markusweigelt]

• Validators for the METS application profile
• Testing environment with test for all validators
• Extend settings of plugin tx_dlf with configuration for [DOMDocumentationValidation middleware] (https://github.com/kitodo/kitodo-presentation/blob/main/Classes/Middleware/DOMDocumentValidation.php) using the XML-Schemes Validator and the ApplicationProfileValidationStack

It can be tested by calling the validation middleware with a faulty METS file:
https://example.com?middleware=dlf/domDocumentValidation&url=https://3drepo.eu/modelupload/b5df7cd550f64e818943ad96fff7e902metsmods.xml

which results in JSON Reponse

  "valid": false,
  "results": {
    "XML-Schemes Validator": [
      "Element '{http://www.loc.gov/METS/}mdWrap', attribute 'MDTYP': The attribute 'MDTYP' is not allowed.\n",

    ]
  }

@beatrycze-volk The implementation works in Typo3 11, and corresponding tests have been written.
I did not explicitly run the tests for Typo3 10, as the old testing framework is required for that, and it does not work easily. I have skipped this adjustment for now since we are working with Typo3 11 and will soon be moving to Typo3 12.

Will this validation also use the DDB schematron validation? We already have a script which does that.

This is not part of this PR and has already been implemented: https://kitodo.github.io/kitodo-presentation/Developers/Validation.html#saxonxsltosvrlvalidator.

The DomDocumentValidation middleware (https://kitodo.github.io/kitodo-presentation/Developers/Validation.html#domdocumentvalidation-middleware) can, among other things, be configured with SaxonXslToSvrlValidator.

The validation documentation (https://kitodo.github.io/kitodo-presentation/Developers/Validation.html#) generally provides clarification in this regard. If anything is missing or there are questions, I would appreciate your feedback.

Thanks. I did not know that this middleware exists.

It hasn’t been around for very long and isn’t included in any release yet.
