The stackup export problem

[Roy-debug-hub]

When I used the customised Djordjevic Sarkar model material in the stackup，the dielectric constant and loss angle tangent information of the frequency variable material was missing from the xml file exported by the edb.stackup.export method.

@Roy-debug-hub thank you for contacting sorry for the delay.
I see you are exporting xml file, is this format fixed for your automated workflow ?
If you need to have DS model compatible ready to import in AEDT, the EDB parameters are converted into equation. This feature is not supported. However PyEDB support DS model of course. Would json format would be acceptable instead of xml ? Then all parameters should be kept.
