+provided by the Spectra, QFeatures and related packages.  Along with raw data
+representations, links to original data files and sample annotations,
+additional metadata or annotations can also be stored within the
+@code{MsExperiment} container.  To guarantee maximum flexibility only minimal
+constraints are put on the type and content of the data within the
+containers.")
