Trying to work out how to escape a hyphen in an XML Tag in Azure SQL Analytics
...but KQL chokes on the hyphen and I don't know how to escape it to make it work

Please see: https://docs.microsoft.com/en-us/azure/data-explorer/kusto/query/schema-entities/entity-names#identifier-quoting
for example: DeadlockXML.deadlock['process-list'].waitresource
