Although some subsystem declare support for expression on certain attributes, they actually don't support it.
As en example see datasources > pool > max-pool-size.
The DMR description says it supports expressions on this attribute:
"max-pool-size" => {
"type" => INT,
"description" => "The max-pool-size element specifies the maximum number of connections for a pool. No more connections will be created in each sub-pool",
"expressions-allowed" => true,
"nillable" => true,
"default" => 20,
"access-type" => "read-write",
"storage" => "configuration",
"restart-required" => "no-services"
},
But then writing an expression value yields an exception
