This is a top-level element; it can only occur as a child of the root element of your stylesheet. It has two different functions:
If you provide a name attribute,
you create a named numeric format that can be
used in the format-number()
function.
If you don't provide a name attribute, the
it defines the default format used for
all numbers.
Aside from the name attribute, the other
attributes are not discussed here. They are chiefly
useful for non-USA languages. Refer to the
XSLT
specification for more details.
