@rasmus Thanks - I looked in phpinfo and the libxml version was 2.6.32 - I'll
ask
Dreamhost about upgrading.

This doesn't actually have much to do with PHP. This completely depends on
whether the version of libxml2 you are using has support for this part of
HTML5.
I haven't looked into it, but I know there were HTML5 additions in libxml2
version 2.8.0. So in order to track this down, figure out which version of
libxml2 you are using. Head over to http://xmlsoft.org/ and see if there is a
more recent version that handles your case. If there isn't, open a feature
request with them. If there is, ask Dreamhost to update their libxml2.

Description:
------------
HTML data attribute names can contain periods:
`<p data-1.5>This is valid in HTML5</p>`
DOMDocument::loadHtml does not properly parse the line above due to the period.
It changes the 1.5 to 1 and/or throws an error:
Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: error parsing
attribute
name in Entity

I am using Dreamhost:
PHP version: 5.3.13 (FastCGI)
PHP build date: 2012-06-07
Test script:
---------------
<?php
# this throws an error:
$dom = new DOMDocument;
$dom->loadHtml('<a data-1.5="value"></a>');
echo $dom->saveHtml();
# this works fine:
$dom = new DOMDocument;
$a = $dom->createElement('a');
$a->setAttribute('data-1.5', 'value');
$dom->appendChild($a);
echo $dom->saveHtml();
