This meta-template is just like Template:Tl with three exceptions:
- It takes a content parameter containing wikitext to be placed within a span element before the superscripted notice.
- It takes a span-class parameter specifying the HTML class name for the [[Span element in HTML| span element]].
- It gives special priority over text rather than the other way around.
The spanned content is displayed like this.
This is a separate template for now because this is an idea imported from the Italian Wikipedia ([[:it:template:cn|Template:Lang]]). Eventually, if this idea takes off, this mechanism could be folded into Template:Tl.
