Lynne, can your mod be made compatible with this template edit:

Now, when we use your mod and this template edit have double information in Google microdata as we have two breadcrumbs.
Is there a way that your mod doesn't use changed template with microdata, but retain functionality of breadcrumb? Or otherwise, that your mod (i.e. breadcrumb created with your mod) uses microdata and upper breadcrumb use original template?
It would be great to use microdata and your mod, but I'm worrying that doubling of this information would hurt SEO and it also looks puzzling in Google results page.
