Introduction of variables in lcdsl

[EaseRider]

I have the following configuration:

abstract swtbot configuration Base-UI-Test {
	product MyProduct;
	content-provider "${workspace_loc:MyProduct}/target/classes/product.product";
}
swtbot configuration My-Plugin-UI-Test : Base-UI-Test {
	plugin MyPlugin;
	workspace "${workspace_loc:/MyPlugin}/target/swt-workspace";
	
	test {
		runner junit4;
		container '/MyPlugin';
	}
}

and with variables I would like to be able to do something like this:

abstract swtbot configuration Base-UI-Test {
	product MyProduct;
	content-provider "${workspace_loc:MyProduct}/target/classes/product.product";
	
	workspace "${workspace_loc:/$testPlugin}/target/swt-workspace";
	
	test {
		runner junit4;
		container '/$testPlugin';
	}
}
swtbot configuration My-Plugin-UI-Test : Base-UI-Test {
	plugin MyPlugin;
	var testPlugin="MyPlugin";
}

I'm not sure what all is possible within the editor for pre validating the code.

Maybe it would even be possible in Non-String arguments for:
plugin $testPlugin;
