title: Tagged Value Type - Collection of Structured Types in Enterprise Architect
body: <p>Is it possible in Enterprise Architect to define as Tagged Value Type collection of some structured types? </p>
  
  <p>For example if i need to extended Table's attributes with collection of N addresses (street, number, city) - hypothetical example:</p>
  
  <pre><code>Table: Person
  Tagged Value: List of addresses -
                  West Street, 1, New York
                  South Street, 2, New York
                  East Street, 3, New York
  </code></pre>
  
  <p>In general i want to simulate in EA what is known in PowerDesigner as Extended Composition of Extended Subobjects.</p>
  
  <p>I followed suggestion to use RefGUIDList, what seems to be most close to my use case but failed as well:</p>
  
  <ol>
  <li>I created Stereotype Address based on Class Metaclass and imported UML Profile containing this metatype to my data model:<br>

  <li>I defined Tagged Value Type List of Addresses as:
  <a href="https://i.stack.imgur.com/CCEGR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CCEGR.png" alt="enter image description here"></a></li>
  <li>I created a pair of Address objects and expected to be able to select between them when tagging table Person, but it did not work and no address showed up.</li>
  <li>When removing filter for Types and Stereotypes from Tagged Value Type definition i was able to select Addresses between all objects in model:

  </ol>
  
  <p>This behaviour is far from PowerDesigner's Extended Compositions functionality. In addition, i need to be able to create new Address right during editing Tagged Value List of Addresses and not before...</p>
