Defined in:
lib/ea/sources/xmi/tag_builder.rb

Overview

Extracts tagged values from the <xmi:Extension><tags><tag/> block. The xmi gem does not expose Sparx tags directly, so we parse the raw XML once and group tags by their modelElement attribute. Each tag's value is truncated at the first # (EA encodes notes after that marker).
