# xsl:preserve-space

The `xsl:preserve-space` element is used at the top level of the stylesheet to define elements in the source document for which white-space nodes are significant and should be retained.

The `elements` attribute is mandatory, and defines a space-separated list of element names. The value "*" may be used to mean "all elements"; in this case any elements where whitespace is not to be preserved may be indicated by an xsl:strip-space element.
