There are a couple ways you can handle this in clay. The resource
bundle is a JSP tag in JSF which didn't work in Clay. Manfred
Kluge contributed a resource bundle component that solves this
problem.
Shale core also has a managed bean that behaves
like a JSF map wrappered resource bundle. It's in the utils package
(LoadBundle). Craig wrote this one so the java doc is pretty
good. The cool thing about the managed bean solution is
that you can specify a scope.
So, if you used the bundle component you might consider:
<span jsfid="loadBundle" basename="org.apache.shale.usecases.view.Bundle"
var="messages"/>
<title>#{messages['@title']}</title>

I think that I gave the graphic image clay component XML definition
a jsfid of "image".

This is a good chance to talk about a new shale remoting feature that
allows you to access static resources like images and style sheets from
the class path. I created a couple components in the rolodex usecase
that pull images from the class path to demonstrate. I really like this idea
because you can create a component library that is self contained and
self registering. Just drop it into the project and it contains all the
resources.
The "static" folder is the default convention and the rest is the class path.
headerSorter.ascImage=/static/org/apache/shale/usecases/rolodex/up.gif.faces
headerSorter.descImage=/static/org/apache/shale/usecases/rolodex/down.gif.faces

The extreme HTML rolodex example shows how this can be done:
<table jsfid="dataTable" class="contacts" value="[EMAIL
PROTECTED]" var="e" rows="5" first="0" headerClass="contactsHeader"
rowClasses="contactsRow1, contactsRow2" allowBody="true">
<caption jsfid="webPager" prevPageStyleClass="linkPrev"
pageLinksStyleClass="links"
nextPageStyleClass="linkNext"
captionStyleClass="caption" facetName="header"
allowBody="false">
Mock Page Links
</caption>
<tbody id="name" jsfid="column" class="contactsHeader"
allowBody="true">
<th jsfid="headerSorter" facetName="header"
allowBody="false" value="#{messages['rolodex.contactTable.nameColumn.title']}"
sortBy="name">
Contacts
</th>
<tr jsfid="webPager" prevPageStyleClass="linkPrev"
pageLinksStyleClass="links"
nextPageStyleClass="linkNext"
captionStyleClass="caption" facetName="header"/>
<tr jsfid="commandLink" value="#{e.name}" action="[EMAIL
PROTECTED]" immediate="true" allowBody="true">
<td jsfid="param" name="selectedName"
value="#{e.encodedName}" allowBody="false">
<a href="#">ABC Company</a>
</td>
</tr>
</tbody>
</table>
>
> or something similar. Is that possible?

Depending on how clean you want your HTML, you can add the JSF component
specific properties in an XML file or in the HTML. The example is also defined
using a more conservative HTML pure approache:
HTML template:
<span jsfid="contactTable">
<table class="contacts">
<tr class="contactsHeader">
<td>
Contacts
</td>
</tr>
<tr class="contactsRow1">
<td>
<a href="#">ABC Company</a>
</td>
</tr>
<tr class="contactsRow2">
<td>
<a href="#">XYZ Company</a>
</td>
</tr>
</table>
</span>
XML Config:
<component jsfid="nameColumn" extends="column" id="name">
<element renderId="1" jsfid="headerSorter" facetName="header">
<attributes>
<set name="value"
value="#{messages['rolodex.contactTable.nameColumn.title']}" />
<set name="sortBy" value="name"/>
</attributes>
</element>
<element renderId="2" jsfid="commandLink">
<attributes>
<set name="value" value="#{e.name}" />
<set name="action" value="[EMAIL PROTECTED]" />
<set name="immediate" value="true"/>
</attributes>
<element renderId="1" jsfid="param">
<attributes>
<set name="name" value="selectedName"/>
<set name="value" value="#{e.encodedName}"/>
</attributes>
</element>
</element>
</component>

You can use myfaces components in Clay. Others might be
able to share their experiences. Another option might be the
Clay for each component. The bodyJsfid holds the
template you want included for each row in the list.
It might look something like this:
<table jsfid="clayForEach" var="e" value="mybean.bugs"
bodyJsfid="classpath*:org/acme/bugslist.html" allowBody="false">
<tr><td>Mock row
</table>
buglist.html
<tr><td>#{e.bugName}</td><td>#{e.comment}</td></tr>
