\title{Generates parameter sets from XML node.}
\description{
 Fetches a list of all parameter sets for a model, given
StudentModel, EvidenceModel or LinkModel xml tag.
}
\usage{getParameterSetsForModel(modelXML, chatty=FALSE)
}

\arguments{
  \item{modelXML}{An XML node from an Assessment Model Description tag
    refering to an Student, Link or Evidence model.}
  \item{chatty}{A logical value, if true, then progress messages about
    files read will printed.}
}
\details{
  This takes an XML node from an Assessment Model Description describing
  one model.  It reads and parses the XML in the associated GM file.  
  It then builds a list of \code{parameterVector} objects corresponding
  to the distributions in the model.

  Note that it is assumed that the GM files are in the current working
  directory.  Thus it is usually necessary to call \code{setwd} to set
  the R working directory to the one containing the AMD and all of the
  GM files before proceding.
}
\value{
A list of \code{parameterSet} objects corresponding to the distributions
in the model.  Only DiBello--Samejima distributions (which use vector
valued parameters) are retained, others are removed.
