Hi,

actualliy, it does not. :(

@Root
public class Data {
	@Attribute
	public double value;

	@Transient
	int stuff;
	
	@Replace
	Object replace() {
		System.out.println("replace called");
		return Double.valueOf(this.value);
	}
}

public class RootClass {
	@Attribute
	Object data;

	// ...
}

But maybe this is not the right way... I think I understand now, that 
replace is not meant for this.

However, using Transform, i can achieve the desired xml.
There is just one little problem:
I need to define a custom Matcher for the Persister (to map 
DataTransform to Data), I think it would be better if I could annotate 
Data with the information about the Transformer.
