As a data point, the WebKit implementation (used by Safari and Chrome) doesn't currently enforce any limits (other than those imposed by running out of memory).<div><br></div><div>-atw<br><br><div class="gmail_quote">On Fri, Oct 23, 2009 at 12:02 AM, Ian Hickson <span dir="ltr"><<a href="mailto:ian@hixie.ch">ian@hixie.ch</a>></span> wrote:<br>

</div></div>There are probably implementation-specific limits, but HTML tries to not<br>
say what the limits should be, since it's hard to know what they should<br>

almost certainly vary over time.<br>
