Steps to reproduce: Create a new DMN file Create DMN decision "Decision-1" Create DRD with the name "new-diagram" (DRD Actions -> Create) Rename "new-diagram" to "new/diagram" (Decision Navigator -> DRDs -> Pencil icon) Execute `mvn kie:validateDMN` in the project root What happens:   [ERROR] One of the supplied DMN Models has failed validation; cannot proceed to validation of the remaining DMN Models. [ERROR] DMN: Failed XML validation of DMN file: cvc-datatype-valid.1.2.1: 'dmnshape- new /diagram-_BA38A888-E918-416E-8BF7-AE219116F843' is not a valid value for 'NCName' . (DMN model failed XML schema validation)  [ERROR] DMN: One of the supplied DMN Models has failed validation; cannot proceed to validation of the remaining DMN Models. (DMN Validation stopped on failed validation for some DMN Model)  What I expect:   The validation should pass. Note: If I change the name to "new-diagram" validation check pass. It looks like "/" and "," are invalid characters for DRD names.
