Mark Anderson commented on AMQ-6120:
------------------------------------
I think you are correct.
Further investigation shows that it doesn't even work with simple property
placeholders e.g
{code:xml}
<amq:timedSubscriptionRecoveryPolicy recoverDuration="${my.value}" />
{code}
giving the same validation exception.
I see that for the "persistent" attribute on "amq:broker" the type is
"xs:string" and these is a custom BooleanEditor. In this case a placeholder can
be used but SPEL doesn't seem to work.
Is a similar solution viable? Even if SPEL couldn't be supported using
placeholders would be useful. However, would you need to change the schema type
for every property you want to set via a placeholder?

> <amq:timedSubscriptionRecoveryPolicy recoverDuration="#{
