Generating Go code from BPMN schemas

Hello! I'm trying to generate Go code based on the BPMN schemas (they can be found in the previous link - BPMN20.xsd being the main one).

Here is the generated Go code for the BPMN20.xsd schema:

// Copyright 2020 The xgen Authors. All rights reserved.
//
// DO NOT EDIT: generated by xgen XSD generator
//

package schema

import (
    "encoding/xml"
)

// Definitions ...
type Definitions *TDefinitions

// TDefinitions ...
type TDefinitions struct {
    XMLName                xml.Name         `xml:"tDefinitions"`
    IdAttr                 string           `xml:"id,attr,omitempty"`
    NameAttr               string           `xml:"name,attr,omitempty"`
    TargetNamespaceAttr    string           `xml:"targetNamespace,attr"`
    ExpressionLanguageAttr string           `xml:"expressionLanguage,attr,omitempty"`
    TypeLanguageAttr       string           `xml:"typeLanguage,attr,omitempty"`
    ExporterAttr           string           `xml:"exporter,attr,omitempty"`
    ExporterVersionAttr    string           `xml:"exporterVersion,attr,omitempty"`
    Import                 []*TImport       `xml:"import"`
    Extension              []*TExtension    `xml:"extension"`
    RootElement            []*TRootElement  `xml:"rootElement"`
    BpmndiBPMNDiagram      []*BPMNDiagram   `xml:"bpmndi:BPMNDiagram"`
    Relationship           []*TRelationship `xml:"relationship"`
}

// Import ...
type Import *TImport

// TImport ...
type TImport struct {
    XMLName        xml.Name `xml:"tImport"`
    NamespaceAttr  string   `xml:"namespace,attr"`
    LocationAttr   string   `xml:"location,attr"`
    ImportTypeAttr string   `xml:"importType,attr"`
}

Also, here is an example BPMN file:

<?xml version="1.0" encoding="UTF-8"?>
<bpmn:definitions xmlns:bpmn="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:dc="http://www.omg.org/spec/DD/20100524/DC" xmlns:di="http://www.omg.org/spec/DD/20100524/DI">
   <bpmn:process id="Process">
      <bpmn:startEvent id="foo" name="foo">
         <bpmn:extensionElements>
            <foo/>
         </bpmn:extensionElements>
         <bpmn:outgoing>Foo</bpmn:outgoing>
         <bpmn:messageEventDefinition id="foo" messageRef="foo" />
      </bpmn:startEvent>
      <bpmn:task id="foo4" name="foo">
         <bpmn:extensionElements>
            <foo/>
         </bpmn:extensionElements>
         <bpmn:incoming>foo</bpmn:incoming>
      </bpmn:task>
      <bpmn:sequenceFlow id="foo" sourceRef="foo" targetRef="foo" />
   </bpmn:process>
   <bpmn:message id="foo" name="foo" />
   <bpmndi:BPMNDiagram>
      <bpmndi:BPMNPlane bpmnElement="Process">
         <bpmndi:BPMNShape bpmnElement="foo">
            <dc:Bounds x="32.84375" y="47.5" width="36" height="36" />
         </bpmndi:BPMNShape>
         <bpmndi:BPMNShape bpmnElement="foo">
            <dc:Bounds x="214.84375" y="100.5" width="100" height="80" />
         </bpmndi:BPMNShape>
         <bpmndi:BPMNEdge bpmnElement="foo">
            <di:waypoint x="50.84375" y="65.5" />
            <di:waypoint x="264.84375" y="140.5" />
         </bpmndi:BPMNEdge>
      </bpmndi:BPMNPlane>
   </bpmndi:BPMNDiagram>
</bpmn:definitions>

The issue I have is that I can't figure out how to unmarshal definitions elements (they appear in the generated code as type Definitions *TDefinitions). Shouldn't they be documented with `xml:"definitions"` in order for the XML parser to be able to parse them? I'm new to go so it's very possible that I'm missing something here.

Thank you in advance!
