Is there a constructor function for xs:numeric?

The intro to section 18 says:

Constructor functions are defined for all user-defined named simple types, and
for most built-in atomic, list, and union types. The only named simple types
that have no constructor function are those that have no instances other than
instances of their derived types: specifically, xs:anySimpleType,
xs:anyAtomicType, and xs:NOTATION.

which would suggest yes (unless one argues that xs:numeric is neither a
user-defined type nor a built-in type).

But no constructor function is listed in 18.4; constructors for all other types
in the xs namespace are explicitly enumerated.

Although there's little practical use for the function, consistency really
demands that it exists, and we should therefore list it in 18.4.
