"trash" section
Configures project trash behaviour. In earlier versions it was not allowed to delete work items permanently from trash. Staring from version 9.1.0, it is configurable (not allowed by default). If you delete items from the trash then it may have effect on baselines.
A typical example
"trash": {
"possibleToDeleteOnlyItems": true
}
Attributes
