as

<template>: If an as attribute is present, the as attribute defines the required type of the result.
<variable>: specifies the required type of the variable
<param>: specifies the required type of the parameter
<with-param>: It is possible to have an as attribute on the xsl:with-param element that differs from the as attribute on the corresponding xsl:param element describing the formal parameters of the called template. In this situation, the supplied value of the parameter will first be processed according to the rules of the as attribute on the xsl:with-param element, and the resulting value will then be further processed according to the rules of the as attribute on the xsl:param element.
<function>: the required type of the result of the function
