Are these two (Seam decorate tag and Facelets ui:decorate) supposed to be similar? For example, let's take the following template (taken from Seam docs) that decorates input fields with errors:

template.xhtml:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:s="http://jboss.com/products/seam/taglib">
 <s:span style="#{invalid ? 'color:red' : ''}">
 <ui:insert name="label" />
 <s:span rendered="#{required}"> *</s:span>
 </s:span>
 <s:span>
 <s:validateAll>
 <ui:insert />
 </s:validateAll>
 </s:span>
</ui:composition>

When we're using ui:decorate, there are two columns created in the table, one for label, another one for input field (but no error decoration, obviously):

<h:panelGrid columns="2">
 <ui:decorate id="username" template="template.xhtml">
 <ui:define name="label">Username:</ui:define>
 <h:inputText value="#{user.username}" required="true" />
 </ui:decorate>
</h:panelGrid>

When we're using s:decorate, it results in only one column being created, with both label and input field in it.

<h:panelGrid columns="2">
 <s:decorate id="username" template="template.xhtml">
 <ui:define name="label">Username:</ui:define>
 <h:inputText value="#{user.username}" required="true" />
 </s:decorate>
</h:panelGrid>

Is this a desired behavior? I wonder whether s:decorate is supposed to behave the same way in respect to its child components...
