---## Meta Data Rendering

Various meta data can be stored in topics - MetaDataDefinition

This is rendered using the %<nop>META% variable.  This is mostly used in the =view=, =preview= and =edit= scripts.

At present support is fairly basic:
  | *Variable usage:*	| *Comment:*  |
  | %<nop>META{"form"}% | Show form data, see [[TWikiDocumentation#Form_Templates][Form Templates]] |
  | %<nop>META{"attachments"}% | Show attachments, excluding hidden ones |
  | options for attachments: |
  | all="on" | Show all attachments i.e.  including hidden ones |
  | %<nop>META{"moved"}% | Details of any topic moves |
  | %<nop>META{"parent [options]"}% | Show topic parent |
  | options for parent: |
  | dontrecurse="on" | By default recurses up tree, this has some cost |
  | prefix="..." | Prefix that goes before parents, but only if there are parents, default "" |
  | suffix="..." | Suffix, only appears if there are parents, default "" |
  | seperator="..." | Seperator between parents, default is " > " |

Possible future additions:
	* Rendering of form data to alternate formats e.g. bullet lists
	* Specify a template to be used for rendering
