<!-- Here we define some interesting new datatypes:
|
|
- anyTEXT may have embedded XHTML (conforming HTML)
|
|
- astroYear is an epoch in Besselian or Julian year, e.g. J2000
|
|
- arrayDEF specifies an array size e.g. 12x23x*
|
|
- dataType defines the acceptable datatypes
|
|
- ucdType defines the acceptable UCDs (UCD1+)
|
|
- precType defines the acceptable precisions
|

- yesno defines just the 2 alternatives
