title: Hard and Soft Transclusions

A <<.def "hard transclusion">> is a [[transclusion|Transclusion]] that can be detected by a superficial examination of WikiText.

A transclusion is <<.def "soft">> if it is:

* contained in text [[trancluded|Transclusion]] from elsewhere
* supplied via a [[macro|Macros]], [[procedure|Procedures]] or [[variable|Variables]]
* generated by a [[transclude widget|TranscludeWidget]] whose <<.attr $tiddler>> attribute is a transclusion, macro or variable

<$macrocall $name=".warning" _="""Soft transclusions are not detected by transclusion-related filter operators <<.olink transcludes>> and <<.olink backtranscludes>>."""/>

This concept is analogous to [[Hard and Soft Links]].
