I think of <f:passThroughAttribute> as being somewhat similar to
<f:attribute>, which has never supported a disabled attribute. I don't
see the need to add this now (for any of the attribute-related tags).

Along with <f:passThroughAttribute>, we also introduced the following
shorthand syntax for specifying pass through attributes:
<h:inputText value="#{myBean.value}" p:aria-required="true"
p:aria-invalid="true"/>
Where the "p:" alias is mapped to the
"
http://xmlns.jcp.org/jsf/passthrough" namespace.
This seems reasonably simple to me.
Alternatively, if you are primarily specifying passthrough attributes,
you can flip things around by taking advantage of passthrough elements, eg:
<input aria-required="true" aria-invalid="true"
jsf:value="#{myBean.value}"/>
Where the "jsf:" alias is mapped to the "
http://xmlns.jcp.org/jsf"
namespace.
