[iip] Customised counter styles are unavailable (#93)

r12a has just created a new issue for https://github.com/w3c/iip:

== Customised counter styles are unavailable ==
Two CSS counter styles are defined in the document <a href="https://w3c.github.io/predefined-counter-styles/#devanagari-styles">Ready-made Counter Styles</a>: <code class="kw" translate="no">devanagari</code> and <code class="kw" translate="no">hindi</code>.  Only the first is defined also in the <a href="https://www.w3.org/TR/css-counter-styles-3/#simple-numeric">CSS Counter Styles specification</a>, the other relies on the user-defined mechanism specified in that spec in order to be applied.

The <code class="kw" translate="no">devanagari</code> counter style is not supported by <span class="fail">Edge</span> (or <span class="fail">IE</span>), but is supported by <span class="pass">Firefox</span>, <span class="pass">Chrome, and Safari</span>. (In the case of failure, the style falls back to ordinary european decimal numbering.)

The hindi style is only supported by browsers that support the user-defined mechanism, and that currently only includes Firefox.
