Describe the bug
According to “IDTA-01003-a-3-0_SpecificationAssetAdministrationShell_Part3a_DataSpecification_IEC61360”, the id of the Data Specification IEC61360 Template is https://admin-shell.io/DataSpecificationTemplates/DataSpecificationIec61360/3/0
By using the id, an error message in the Package Explorer (v2024-02-27) is saying that the
Data specification Reference could not be identified. Thus, no content attributes could be provided.

Expected behavior
By changing the letters IEC in the id to uppercase, Package Explorer is showing the attributes as expected.
