I am using Wordpress version 3.5.1
I am using Wordpress SEO version 1.4.2
When I run my website through a validator, they always complain about the xhtml attributes in the breadcrumbs.
There is a microformat for breadcrumbs, found here: http://microformats.org/wiki/breadcrumbs-formats
Which would make the breadcrumbs something like this:
<div class="breadcrumbs" itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
<a class="breadcrumb-link" href="/" itemprop="url">
<span itemprop="title">Home</span>
</a> >
<div itemprop="child" itemscope itemtype="http://data-vocabulary.org/Breadcrumb" style="display: inline;">
<a class="breadcrumb-link trail" href="/child" itemprop="url">
<span itemprop="title">Child</span>
</a> >
</div>
</div>
The customers are requesting a lot of HTML5 valid codes with correct microformat use, so something like this would be nice to have as an option.
