Does the ESB XSLT Action support parameters?

Issue

• I'd like to pass parameters into my stylesheets. Is there a way to do this when using the XSLT Action?
• I saw that a patch was created on one of the forums (http://community.jboss.org/thread/164094) to do this but that doesn't work now.
• The code for the parameters looked like this (which doesn't work now):

<property name="xslt-params">
    <xslt-param name="dyn_param" value="my_value_holder">
    <xslt-param name="dyn_param2" value="my_value_holder2">
</property>

• If not, then this will become another CustomAction which isn't a problem. I'm just trying to use as much "out of the box" functionality as possible.
