Edit View: Edit A Page Template
  
    Description

        This view allows you to edit the template's text, upload new
        text, or change the content type and title of the template.

    Template Text

        The text in a template must be well-formed HTML if the content
        type is 'text/html'.  Otherwise, it must be well-formed XML.
        Either way, it may include "TAL":tal.stx or "METAL":metal.stx
        markup containing "TALES":tales.stx expressions.
        
    Controls

        'Title' -- Allows you to specify the Zope title of the template.
        
        'Content-Type' -- Allows you to specify the content-type that
        will be given to renderings of this template.  Also, if the
        content type is 'text/html' (the default) then the template is
        assumed to contain HTML, not XML.  This affects both parsing
        and rendering of the template, and can be overridden by giving
        the template an 'is_html' property. In HTML mode you don't
        need to explicitly declare 'tal' and 'metal' XML namespaces. In
        XML mode you must explicitly declare 'tal' and 'metal' XML
        namespaces, and Zope assumes that your template contains
        well-formed XML.

        'Expand macros when editing' -- Allows you to turn the expansion
        of METAL macros on or off.  This only affects viewing of the
        source code, not rendering.
        
    Buttons and Other Form Elements

        'Save Changes' -- saves changes you make to the body, title, or
          content type.

        'Taller'/'Shorter'/'Wider'/'Narrower' -- make the body textarea
          taller, shorter, wider, or narrower.

        'File' -- upload a file into this template.

    File Upload Details

        Files uploaded into a template must be valid HTML or XML text.
