Defined in:
lib/ea/transformers/uml_to_xmi/id_generator.rb

Overview

Allocates xmi:id values for UML elements during lossy serialization.

Strategy:

1. If the element already has an `xmi_id` (set by the QEA factory
 during parsing), reuse it.
2. Otherwise synthesize a stable `EAID_…` from a counter.

This class is used only by the lossy Transformer path. The full-fidelity QeaToXmi path uses QeaToXmi::GuidFormat to normalize raw EA GUIDs.
