Subject: [xsl] Typing of parameters in XSLT 2.0 From: Andrew Watt <andrew@xxxxxxxxxxxxxx> Date: Wed, 16 Apr 2003 21:16:01 +0100
I was experimenting in Saxon 7.4 with a simple factorial example which
accepts an argument from the command line.
In the absence of an as attribute or a type-information attribute on the
<xsl:param> element the stylesheet seemed to behave in XSLT 2.0 as it did
in XSLT 1.0.
That is convenient but I am not sure that I completely understand the XSLT
2.0 processor's behaviour.
Let's say the command line was java -jar saxon7.jar ..... number=5.
What type is the supplied parameter 5 in XSLT 2.0? I couldn't find a clear
description in the spec.
Is the supplied parameter a string which is then automatically cast to an
XPath 1.0 number?
In the processing of the $number parameter and the variable(s) used to
recursively calculate the factorial it was being treated as some type of
number, since I could perform both subtraction and multiplication on it. An
XPath 1.0 number? Or an xsd:integer??
In the absence of both an as attribute and a type-information attribute is
an XSLT 2.0 processor expected to produce the same behavior as in XSLT 1.0
and automatically treat parameters "intuitively"? Or is the Saxon 7.4
behaviour a carry over from its XSLT 1.0 heritage?
