XML Query Use Cases
W3C Working Draft 08 June 2001
1.1.9.10 Use Case XMP, query 10
The Solution in XQuery passes a sequence of nodes (<price> elements) to the
'min' function. While this is compatible with xf:min's declared parameter-
type of anyType*, I don't think the result is defined, because the relation
"is less than" is not defined on nodes.
For a less dubious solution, replace
{ min($p) }
with
<price>{ min(decimal($p/text())) }</price>
