The registry is published as part of the X Consortium software
release.
The latest version may also be available by sending a message to

NON STANDARDS
The X11R6.4 distribution contains _s_a_m_p_l_e implementations, not
_r_e_f_e_r_e_n_c_e implementations. Although much of the code is believed
to be correct, the code should be assumed to be in error wherever it
conflicts with the specification.
X REGISTRY
The X Consortium maintained a registry of certain X-related items, to
aid in avoiding conflicts and to aid in sharing of such items.

The X Registry and the names in it are not X Consortium standards.
