Missing map_content when generating schema by Lutaml::Model::Schema::XmlCompiler.to_models(schema)

[kwkwan]

Consider we have address schema like:

schema = <<XSD
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="qualified">
  <xs:element name="Address" type="Address"/>
  <xs:complexType name="Address" mixed="true">
    <xs:sequence>
      <xs:element name="City" type="xs:string" minOccurs="0"/>
      <xs:element name="ZIP" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>
XSD

and address content looks like:

address = <<~ADD
<Address>
  Oxford Street
  <City>London</City>
  <ZIP>E1 6AN</ZIP>
</Address>
ADD

When the class definition is generated by Shale::Schema.from_xml([schema]) using the above mentioned schema, the class will look like:

class Address < Shale::Mapper
  attribute :content, Shale::Type::String
  attribute :city, Shale::Type::String
  attribute :zip, Shale::Type::String

  xml do
    root 'Address'

    map_content to: :content
    map_element 'City', to: :city
    map_element 'ZIP', to: :zip
  end
end

However, when the class definition is generated by Lutaml::Model::Schema::XmlCompiler.to_models(schema) using the same schema, the class will look like:

class Address < Lutaml::Model::Serializable
  attribute :city, String, collection: true
  attribute :zip, String, collection: true

  xml do
    root "Address", mixed: true

    map_element :City, to: :city
    map_element :ZIP, to: :zip
  end
end

When we use the class definition generated by Lutaml::Model to parse the address:

Address.from_xml(address).to_xml
=> "<Address><City>London</City><ZIP>E1 6AN</ZIP></Address>"

The content "Oxford Street" will be missing.
