 * The TemplateData editor will not allow you to change a parameter to a blank "$1". Parameters in TemplateData that somehow acquire blank strings as names will not cause issues in the 2010 wikitext editor with TemplateWizard, but neither VisualEditor nor the 2017 wikitext editor will display them at all. This is the only mandatory field in the TemplateData editor.
