RE: [XSLT2.0] IBM-XSLT-111: Implications of using "as" attribute

I agree that the phrase "validated and/or converted" is fuzzy.

I propose to replace the sentence:

In this situation, the computed value of the parameter will be validated
and/or converted twice, first according to the rules of the as attribute
on the xsl:with-param element, and then according to the rules of the as
attribute on the xsl:param  element.

by

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. 

For example, suppose the supplied value is a node with type annotation
xdt:untypedAtomic, and the xsl:with-param element specifies
as="xs:integer", while the xsl:param element specifies as="xs:double".
Then the node will first be atomized and the resulting untyped atomic
value will be cast to xs:integer. If this succeeds, the xs:integer will
then be promoted to an xs:double.

I would be grateful if you could confirm that this clarifies the
specification adequately.
