VOTable is meant to serialize tabular documents in the context of Virtual Observatory applications. This schema corresponds to the VOTable document available from http://www.ivoa.net/Documents/latest/VOT.html Accept UCD1+ Accept also old UCD1 (but not / + %) including SIAP convention (with :) content-role was previsouly restricted as: ]]>; is now a token. Deprecated in Version 1.2 This is a time origin of a time coordinate, given as a Julian Date for the the time scale and reference point defined. It is usually given as a floating point literal; for convenience, the magic strings “MJD-origin” (standing for 2400000.5) and “JD-origin” (standing for 0) are also allowed. The time origin is the offset or the time coordinate to Julian Date. The timeorigin attribute MUST be given unless the time's representation contains a year of a calendar era, in which case it MUST NOT be present. This is the time scale used. Values SHOULD be taken from the IVOA timescale vocabulary (http://www.ivoa.net/rdf/timescale). The reference position SHOULD be taken from the IVOA refposition vocabulary (http://www.ivoa.net/rdf/refposition). Deprecated in Version 1.1 Added in Version 1.2: INFO for diagnostics The 'encoding' attribute is added here to avoid problems of code generators which do not properly interpret the TR/TD structures. 'encoding' was chosen because it appears in appendix A.5 The ID attribute is added here to the TR tag to avoid problems of code generators which do not properly interpret the TR/TD structures Added in Version 1.2: INFO for diagnostics Added in Version 1.2: INFO for diagnostics in several places
