Details
The element typically contains a number of xsl:when elements, each with a separate test condition.
The first xsl:when element whose condition matches the current
element in the source document is expanded, the others are ignored. If none of
the conditions is satisfied, the xsl:otherwise child element, if any, is expanded.
The test condition in the xsl:when element is a boolean expression.
The full syntax of expressions is outlined in XPath Expression Syntax.
