content_info.attributes for vector datasets do not appear in 19139 xml docs

[davemfish]

An MCF section like this:

content_info:
  attributes:
  - abstract: ''
    name: ws_id
    title: ''
    type: integer
    units: ''
  - abstract: ''
    name: subws_id
    title: ''
    type: integer
    units: ''
  - abstract: ''
    name: ws_name
    title: ''
    type: string
    units: ''

The data does not appear to translate through to an xml doc created using pygeometa:

iso_schema = ISO19139OutputSchema()
xml_string = iso_schema.write(self.mcf)

Inspecting the jinja2 template (pygeometa\schemas\iso19139\main.j2) I find this section,

  {% if record['content_info'] %}
  <gmd:contentInfo>
    {% if record['content_info']['type'] == 'image' %}
    <gmd:MD_ImageDescription>
      <gmd:attributeDescription>

And no other content_info['type'] besides 'image' seems to be supported by the template. But the core MCF schema allows for:

    content_info:
        type: object
        properties:
            type:
                type: string
                description: Content type
                enum:
                    - coverage
                    - image
                    - feature_catalogue

I've been using "image" for rasters and "coverage" for vectors.

In addition to content_info['attributes'] MCF also has an attributes section. I'm not certain which of those sections is meant for use with vector attribute tables. Neither section is written out to the XML. See geopython/pygeometa#197
