Template:Xpd0
Expanding demo for a template without parameters, or a parser function with colon and part after the colon, or a variable.
This is a simplified version of Template:Xpdoc, for the case that there is no wikitext after the closing braces.
Examples:
"{{tc}}"
gives "in" [1]{{tc}}
gives in [2]"{{tc}}"
gives "in" [3]"{{msgnw:tc}}"
gives "in<noinclude>{{documentation}}</noinclude>" [4]"{{#expr:2*3}}"
gives "6" [5]"{{CURRENTTIME}}"
gives "10:15" [6]
