# xsl:include

The `xsl:include` element is always used at the top level of the stylesheet. It has a mandatory `href` attribute, which is a URL (absolute or relative) of another stylesheet to be textually included within this one. The top-level elements of the included stylesheet effectively replace the xsl:include element.

`xsl:include` may also be used at the top level of the included stylesheet, and so on recursively.
