<xsl:preserve-space>
The <xsl:preserve-space> element defines the elements in the source document for which whitespace should be preserved. If there is more than one element, separate the names with a whitespace character. Preserving whitespace is the default setting, so this element only needs to be used to counteract an <xsl:strip-space> element.
