Returns true if the two xs:gYear
values have the same starting instant.
xs:gYear
values. Also used in the
definition of the "ne" operator.op:gYear-equal
( $arg1
as xs:gYear
,$arg2
as xs:gYear
xs:boolean
The starting instants of $arg1
and $arg2
are calculated by
supplying the missing components of $arg1
and $arg2
from the
xs:dateTime
template xxxx-01-01T00:00:00
. The function
returns the result of comparing these two starting instants using
op:dateTime-equal
.
Assume that the dynamic context provides an implicit timezone value of
-05:00
. Assume, also, that the xs:dateTime
template is
xxxx-01-01T00:00:00
.
op:gYear-equal(xs:gYear("2005-12:00"), xs:gYear("2005+12:00"))
returns
false()
. The starting instants are
2005-01-01T00:00:00-12:00
and 2005-01-01T00:00:00+12:00
,
respectively, and normalize to 2005-01-01T12:00:00Z
and
2004-12-31T12:00:00Z
.
The expression op:gYear-equal(xs:gYear("1976-05:00"),
xs:gYear("1976"))
returns true()
.
