[xsl] What the default datatype of an stylesheet parameter ?

[Matthieu Ricaud-Dussarget <matthieu.ricaud@xxxxxxxxx>]

Hi all,

When sending a parameter to the stylesheet( from command line with saxon 
for example), I thought it was always a string (which is a pitty when 
you need boolean parameter).

I made a simple test, sending "bar" to parameter foo :
<xsl:param name="foo"/>

I was really astonished to see that
$foo instance of xs:string
returns false()

I then typed the parameter :
<xsl:param name="foo" as="xs:string"/>
and got true()

What was the type of $foo before I casted it with as="xs:string" ?
Has it any type ...?

Thank for your lightening me :-)

Cheers,

Matthieu
