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"/>

In XSLT 1, that is, indeed, an empty string as you anticipated. In XSLT 2, however, that is the declaration of an empty sequence.


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 ...?

Nope. It is bound to the empty sequence and cannot be changed if a binding value is not supplied at invocation time.


Thank for your lightening me :-)

I hope this helps.
