-----------------------------------------------------------
Adding syntactic sugar is unnecessary right now, {{RenderKitUtils}} can be extened
instead.
Let's revisite in the future.
----
There are two other solution then extending {{RenderKitUtils}}:
* adding stateful auxiliary object which would carry {{facesContext}} and {{component}}
references to, e.g.: {{renderingContext}} or {{componentContext}}
* using auxiliary tags, like in case of {{<cdk:renderFacet proposal />}} RF-12260
(but it brings some issues as commented there)

h3. 1) Test if an attribute is present :

{code:java}
public boolean hasAttribute(String attributeName) {
// TODO : test if the attribute is present
}
{code}
h3. 2) Test if a facet is present
Same as before but about JSF facets
{code:xml}
<c:when test="#{component.getFacet('brand') != null and
component.getFacet('brand').rendered}">
{code}
Become
{code:xml}
<c:when test="#{component.hasFacet('brand')}">
{code}
