The method .from_xml does not work as expected

[kwkwan]

Assume I have an xmi file:

test = <<XMI
<?xml version="1.0" encoding="windows-1252"?>
<xmi:XMI xmlns:uml="http://www.omg.org/spec/UML/20131001" xmlns:xmi="http://www.omg.org/spec/XMI/20131001" xmlns:umldi="http://www.omg.org/spec/UML/20131001/UMLDI" xmlns:dc="http://www.omg.org/spec/UML/20131001/UMLDC" xmlns:thecustomprofile="http://www.sparxsystems.com/profiles/thecustomprofile/1.0">
  <xmi:Documentation exporter="Enterprise Architect" exporterVersion="6.5"/>
  <uml:Model xmi:type="uml:Model" name="EA_Model">
    <packagedElement xmi:type="uml:Package" xmi:id="EAPK_C799E047_A10F_4203_9E22_9C47183CED98" name="requirement type class diagram">
    </packagedElement>
  </uml:Model>
</xmi:XMI>
XMI

and I have defined classess like:

module Xmi
  module Uml
    class PackagedElement < Lutaml::Model::Serializable
      attribute :type, :string
      attribute :id, :string
      attribute :name, :string
      attribute :supplier, :string
      attribute :client, :string
      attribute :packaged_element, PackagedElement, collection: true

      xml do
        root "packagedElement"

        map_attribute "type", to: :type, namespace: "http://www.omg.org/spec/XMI/20131001", prefix: "xmi"
        map_attribute "id", to: :id, namespace: "http://www.omg.org/spec/XMI/20131001", prefix: "xmi"
        map_attribute "name", to: :name
        map_attribute "supplier", to: :supplier
        map_attribute "client", to: :client
        map_element "packagedElement", to: :packaged_element
      end
    end

    class UmlModel < Lutaml::Model::Serializable
      attribute :type, :string
      attribute :name, :string
      attribute :packaged_element, PackagedElement, collection: true

      xml do
        root "Model"
        namespace "http://www.omg.org/spec/UML/20131001", "uml"

        map_attribute "type", to: :type, namespace: "http://www.omg.org/spec/XMI/20131001", prefix: "xmi"
        map_attribute "name", to: :name

        map_element "packagedElement", to: :packaged_element, namespace: nil, prefix: nil
      end
    end
  end
end


module Xmi
  class Root < Lutaml::Model::Serializable
    attribute :id, :string
    attribute :label, :string
    attribute :uuid, :string
    attribute :href, :string
    attribute :idref, :string
    attribute :type, :string
    attribute :model, Uml::UmlModel

    xml do
      root "XMI"
      namespace "http://www.omg.org/spec/XMI/20131001", "xmi"

      map_attribute "id", to: :id
      map_attribute "label", to: :label
      map_attribute "uuid", to: :uuid
      map_attribute "href", to: :href, namespace: nil, prefix: nil
      map_attribute "idref", to: :idref
      map_attribute "type", to: :type

      map_element "Model", to: :model,
                           namespace: "http://www.omg.org/spec/UML/20131001",
                           prefix: "uml"
    end
  end
end

module Xmi
  module Sparx
    class SparxRoot < Root
      attribute :id, :string
    
      xml do
        root "XMI"
        namespace "http://www.omg.org/spec/XMI/20131001", "xmi"

        map_attribute "id", to: :id
      end
    end
  end
end

When I run:

require "lutaml/model"
require "nokogiri"
require "lutaml/model/xml_adapter/nokogiri_adapter"


Lutaml::Model::Config.configure do |config|
  config.xml_adapter = Lutaml::Model::XmlAdapter::NokogiriAdapter
end

m = Xmi::Sparx::SparxRoot.from_xml(test)

The packaged_element does NOT parsed as expected:

b(main):276:0> m.model
=> 
#<Xmi::Uml::UmlModel:0x0000000104d2c2d8                                            
 @element_order=["text", "packagedElement", "text"],                               
 @mixed=false,                                                                     
 @name="EA_Model",                                                                 
 @ordered=nil,                                                                     
 @packaged_element=[],                                                             
 @type="uml:Model",                                                                
 @using_default={:type=>false, :name=>false, :packaged_element=>true}>
