docs: Parse the arguments to a SWAP TABLE statement.
  SWAP TABLE statements use simple String attributes
  as the "VoltXML" representation for their target tables.
  They don't need all the complexity of the child table nodes
  used in other kinds of statements.
  SWAP TABLE statements don't bother to populate most of the
  detailed AbstractParsedTable members related to tables.
  The m_tableList is sufficient for SWAP TABLE's minimal
  validation and planning requirements.
