lua-uri-urn-oid - OID URN support for Lua URI library

=head1 Description

The class C<uri.urn.oid> is used for URNs with the NID 'oid', that is, URIs
which begin C<urn:oid:>.  It inherits from the L<uri.urn|lua-uri-urn(3)>
class.

The URI is considered invalid if its NSS doesn't consist only of non-negative
integers separated by full stop characters.  Numbers with leading zeroes
are not allowed (although the number '0' on its own is).  There must be at
least one number.

There is no normalization performed beyound that performed by the C<uri.urn>
class.

=head1 Methods

All the methods defined in L<lua-uri(3)> and L<lua-uri-urn(3)> as supported, as
well as the following:

=over

=item uri:oid_numbers(...)

Get or set the OID as an array of Lua number values.

If a new value is provided then it must be a table containing an array of
at least one number.  All the values in the table must be non-negative
numbers.  Non-integer numbers are rounded down to an integer value.  Strings
containing only decimal digits are also allowed.
