Overview

Serializes the EA-specific content of <xmi:Extension>.

The xmi gem models the structural XMI tree (model, packages, classes, attributes) but does not represent EA's per-element extension metadata. This class produces the inner XML for the <xmi:Extension> element as three sibling sections:

<elements>   — one <element> per package/classifier, carrying
             <model>, <properties documentation="...">,
             <style appearance="..."> and nested <tags>.
<connectors> — one <connector> per relationship, with
             source/target <model> blocks.
<diagrams>   — one <diagram> per diagram, with placed
             <element> children referencing subjects.

The Transformer injects this string into the serialized XMI's empty <xmi:Extension> placeholder.

Sparx XMI is the canonical shape; the xmi gem's parser does not model these sections, so output containing them is not round-trippable through Xmi::Sparx::Root.parse_xml.
