}
\usage{
processOmitCodes(handlers, omitCodes)
}

\arguments{
  \item{handlers}{XML Node objects from the Assessment Model Description
    being processed.}
  \item{omitCodes}{A vector giving recoding to use for missing values.
    Names should be the values in the \code{cpd.xml} file and value

\description{
  Generates the \code{<MissingCode>} elements for a Pretest Description
  from the \code{<MissingCode>} elements from an Assessment Model
  Description.  The assumption is that they will be recoded, the
  \code{omitCodes} argument gives the new coding.   The data sets
  \code{omitCode789}, and \code{omitCodeStrings} contain two common
  cases:  recoding to integers and leaving intact as strings.
}
\section{Side Effects}{
  XML element is written to the file corresponding to the second argument.
