implied source (i.e., current) and target tables, as in

A tag name the identifies the role the interface plays
in the particular capability.  If the value is equal to
"std" or begins with "std:", then the interface refers
to a standard interface defined by the standard

For an interface complying with some registered

resource record.  The interface descriptions in
the standard record can provide default descriptions

is not provided, the meaning of this attribute is

Attributes
QName Type Fixed Default Use Annotation
ANY attribute from ANY namespace OTHER than 'http://www.ivoa.net/xml/VODataService/v1.1'
arraysize vs:ArrayShape 1 optional 
the shape of the array that constitutes the value
 
the default is "1"; i.e. the value is a scalar.
delim xs:string optional 
the string that is used to delimit elements of an array
value when arraysize is not "1".
 
Unless specifically disallowed by the context, 
applications should allow optional spaces to 
appear in an actual data value before and after 
the delimiter (e.g. "1, 5" when delim=",").
 
the default is " "; i.e. the values are delimited 
by spaces.
extendedSchema xs:anyURI optional 
An identifier for the schema that the value given
by the extended attribute is drawn from.
 
This attribute is normally ignored if the
extendedType attribute is not present.
extendedType xs:string optional 
The data value represented by this type can be
interpreted as of a custom type identified by 
the value of this attribute.
 
If an application does not recognize this
extendedType, it should attempt to handle value
assuming the type given by the element's value.
string is a recommended default type.
 
This element may make use of the extendedSchema
attribute and/or any arbitrary (qualified)
attribute to refine the identification of the

size xs:positiveInteger optional 
the length of the fixed-length value
 
This corresponds to the size Column attribute in
the TAP_SCHEMA and can be used with data types
that are defined with a length (CHAR, BINARY).

a description of standard space-time coordinate systems,
positions, and regions.
 
This resource provides a mechanism for registering standard 
coordinate systems which other resources may reference as
part of a coverage descripiton.  In particular, coverage
descriptions will refer to components of the STC
descriptions in this resource via an IVOA identifier.  It
is intended that an application consuming such coverage
descriptions be able to semantically interpret the
identifier without resolving it.  For this reason, once a
standard STC description is registered with this resource 
type, updating the description is strongly discouraged.
