RE: Creating XPath2 functions:passing a set of nodes,

You may use occurrence indicator "*" or "+" in <xsl:param>, such as

<xsl:param ... as="xs:double*">

to indicate that a sequence of double is expected.

Subject:  Creating XPath2 functions:passing a set of nodes, what is
the signature construction?

I am learning XPath2 using Saxon 8.6. I'd like to create a funtion to
compute the standard deviation of the value of a set of nodes. Is there
some special way to construct the signature of the function when the
argument is a set of nodes as opposed to a single node?

I have written a funtion that takes a single node as an argument of type
xs:double. Is there some special way to state that the function will
take a set of nodes of type xs:double, or do I simply state that the
argument will be of type xs:double?
