XMLSerializer ignores value of parameters

The following is inside a component:

ParamValue: delay(time, svalue = null, dvalue = NaN) = 2.2E-4
ParamValue: duration(time, svalue = null, dvalue = NaN) = 4.0E8
ParamValue: amplitude(current, svalue = null, dvalue = NaN) = 7.300000000000001E-10

however when doing

String serialisedModel = XMLSerializer.serialize(lems)

the file shows

<pulseGenerator id="pulseGen1" delay="0ms" duration="100000000s" amplitude="0.08nA"/>

I suspect the problem is caused by the following objects which are also inside the LEMS component model:

XMLAttribute(delay, 0ms) 
XMLAttribute(duration, 100000000s) 
XMLAttribute(amplitude, 0.08nA) 

which I suspect is what is getting used during serialization.
The same information seems to be stored in two places, if XMLAttribute are necessary for whatever reason then the library should reconcile them if the user changes the value of a parameter through the API

lemsParameter.setDoubleValue(...)

which is what we are doing to let the user change the parameters in the model.
Either that or there should be some method that can be called to update the XMLAttributes.
However ideally redundant information should probably be best avoided altogether.

Start by reproducing the issue through XMLSerializer.serialize(lems) after changing values with lemsParameter.setDoubleValue(...), then inspect how XMLAttribute values are used alongside component parameters. Done means serialized delay, duration, and amplitude reflect the updated parameter values without stale XMLAttribute data.
