This {{WPBannerMeta}} subtemplate decides whether the banner instance is on the main templatepage, that is, whether the banner should display in its 'demo' version with all options demonstrated. It performs two checks

		Is the page the BANNER_NAME or subpage?
		No	Yes	No	Yes
		and		and not
Is category=no set?	No		yes	yes
	Yes

1. Is the pagename the |BANNER_NAME=, or is the page a subpage of that page?
2. Is the |category=no parameter set?

And then combines them together either with "and" (default) or another logical operator, eg "or"; this can be specified in the first unnamed parameter.
