Caution: The TemplateData editor will place TemplateData on either the template page or on a documentation subpage. You determine where the TemplateData will be added by opening (editing) the page that you want the TemplateData to be placed on. However, if multiple TemplateData blocks are placed on the same template, then only one of those TemplateData blocks will be used. If there is already TemplateData on a page, then you need to edit the page where the TemplateData was previously placed to avoid accidentally creating multiple blocks of TemplateData.
