PDF documentation build

This change provides the necessary modifications to enable
building of pdf documentation. The resources.py extension
required modification to:
  - prevent attributes from being rendered as stray \items
    outside of a list environment
  - prevent update policies from being rendered as stray
    \items outside of a list environment
  - remove the 'Note:' admonition around the 'Not implemented'
    message when it applies to a sub-property, such as a list.
    The admonition was not rendered as a list item, causing the
    build to fail due to an empty list.
