A transclusion allows to include the content of other zettel into the current zettel.

The transclusion specification begins with three consecutive left curly bracket characters (""''{''"", U+007B) at the first position of a line and ends with three consecutive right curly bracket characters (""''}''"", U+007D).
The curly brackets delimit either a [[zettel identifier|00001006050000]] or a searched zettel list.
You can add some [[attributes|00001007050000]], although a transclusion does not support the default attribute.
Any other characters in this line will be ignored.

This leads to three variants of transclusions:
# Transclusion of the content of another zettel into the current zettel.
  This is done if you specify a zettel identifier, and is called __zettel transclusion__.
# Transclusion of the list of zettel references that satisfy a [[query expression|00001007700000]].
  This is called __query transclusion__.
# Transclusion of the content of an image, referenced by a [[hosted or based|00001007040310#link-specifications]] link / URL.

The first two variants are described on separate zettel:
* [[Zettel transclusion|00001007031110]]
* [[Query transclusion|00001007031140]]
