#### 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-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-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.

If VOTable 1.3 output is in force, the `*-binary-*` options will be replaced by `*-binary2-*`.
