docs: Optional parameter defining which rows are selected when the datatable is initially rendered. If this attribute is an integer, it's the row index. If it's a string, it's a jQuery expression. If it's another object, it's compared to the loop var.  Automatically sets selection='true' and selected-items='row'. <P>
  @return Returns the value of the attribute, or null, if it hasn't been set by the JSF file.
