| Parameters in XProc are strings.

| <p:param name="person" as="element()"/>

I assume you meant, you can write <xsl:param ...>

No, we don't have to. We simply won't be able to pass parameters of
that type in V1.0 of XProc.

I've been using XSLT for years and the fact that no implementation
I've used allows me to pass anything but strings as parameter values
From the command line has never been a significant problem for me.

We've already decided that we're not going to mandate a particular
data model.
