/**
 * @class HTMLFormat
 * @ingroup Format
 * @brief HTMLFormat realizes the HTML request/response format. Since all data
 * from the external representation arrives in form fields, grouping of values
 * has to be done via the field names. So Nodes are represented by their values
 * whose field names are of the form value-<datatype>-<name>-<oid>. All of these
 * values will be removed from the request and replaced by Node instances
 * representing the data. The each node is stored under its oid in the data array.
