Create R code to coerce an R value to a value appropriate for an XML Schema type

This function is used when programmatically generating R functions to interface to Web services and other facilities which involve serializing R values from users to XML.

Usage

coerceArgumentCode(id, type)

id	the name of the variable to be coerced
type	the SchemaType-class describing the XML schema type expected.
