In broker.xml, we can't use '/' or '_' in queue names. However, these characters seem to be OK in address names. The problem may lie in the XML schema, which has the address name specified like this:

<xsd:attribute name="name" type="xsd:string" use="required">

but the queue name specified like this:

<xsd:attribute name="name" type="xsd:ID" use="required"/>

In the short term, simply changing the definition of the queue name to use xsd:string may suffice (provided that the broker itself accepts the names under consideration). However, it might be more appropriate to define the exact set of characters that is allowed – see AMQDOC-2609.
