\usage{
validation_ui(id, max_height = NULL, ...)

validation_server(id, data)
}
\arguments{
\item{id}{Module's ID.}

\item{max_height}{Maximum height for validation results element, useful if you have many rules.}

\item{...}{Arguments passed to \code{actionButton} or \code{uiOutput} depending on display mode,
you cannot use \code{inputId}/\code{outputId}, \code{label} or \code{icon} (button only).}

\item{data}{a \code{reactive} function returning a \code{data.frame}.}
}
\value{
\itemize{
\item UI: HTML tags that can be included in shiny's UI
\item Server: a \code{list} with two slots:
\itemize{
\item \strong{status}: a \code{reactive} function returning the best status available between \code{"OK"}, \code{"Failed"} or \code{"Error"}.
\item \strong{details}: a \code{reactive} function returning a \code{list} with validation details.

Check that a dataset respect some validation expectations.
