#### 4.1.2.3 VOTable

When a table is saved to VOTable format, a document conforming to the VOTable specification containing a single TABLE element within a single RESOURCE element is written. The version of the VOTable specification according to which the output is written can be controlled using the `votable.version` system property.

There are a number of variants which determine the form in which the table data (DATA element) is written:

votable-tabledata
  TABLEDATA element (pure XML)
votable-binary-inline
  BINARY element containing base64-encoded data within the document
votable-binary2-inline
  BINARY2 element containing base64-encoded data within the document. Not available for VOTable version 1.2 or earlier.
votable-fits-href
  FITS element containing a reference to an external newly-written FITS file (with a name derived from that of the VOTable document)
votable-binary2-href
  BINARY2 element containing a reference to an external newly-written binary file (with a name derived from that of the VOTable document) Not available for VOTable version 1.2 or earlier.
votable-binary-href
  BINARY element containing a reference to an external newly-written binary file (with a name derived from that of the VOTable document)
votable-fits-inline
  FITS element containing base64-encoded data within the document

See the VOTable specification for more explanation of what these variants mean. They can all be read by the VOTable input handler.
