[xsl] xdt:dayTimeDuration casting issue

["Laura Porter" <lporter@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I am using Saxon 8.7.3J and having an issue casting a string to
xdt:dayTimeDuration for use in  days-from-duration()

The error I'm getting is:

Cannot find a matching 1-argument function named
{http://www.w3.org/2005/xpath-datatypes}dayTimeDuration()

I've checked that the namespace is correct
(xmlns:xdt=http://www.w3.org/2005/xpath-datatypes). The exact usage is:

<xsl:value-of
select="days-from-duration(xdt:dayTimeDuration(dates/duration))"/> where
dates/duration is P0Y3M3DT12H

Casting to xs:duration works perfectly well: <xsl:value-of
select="xs:duration(dates/duration)"/> results in P0Y3M3DT12H0M0S

Can anyone give me an indicator of where I'm going wrong? Thanks in
advance.

Laura.
