Google Chrome presents the recipe data via XHTML tags.
A tag's attributes don't need to be prefixed when those attributes belong to the ele-
ment.Forexample,
qty
isnotprefixedin
<r:ingredient qty="2">
.However,
aprefixisrequiredforattributesbelongingtoothernamespaces.Forexample,suppose
you want to add an XHTML
style
attribute to the document's
<r:title>
tag, to
provide styling for the recipe title when displayed via an application. You can accom-
plishthistaskbyinsertinganXHTMLattributeintothetitletag,asfollows:
<r:title
h:style="font-family: sans-serif;">
. The XHTML
style
attribute
has been prefixed with
h:
because this attribute belongs to the XHTML language
namespace and not to the recipe language namespace.
