It i my inderstanding that a sub grid may only be load by and “XML file” my question is can it be an XML string ?
While most simple way is to use separate XML file, component provides two events, which allows to change behavior and load sub-grid from any other source.

Something similar to next can be used.
subgrid.loadXMLString(data); // use the current data as configuration xml
return false; // prevent default behavior
