SPeL in tag attributes when using Spring context

Hi All,

I'm trying to configure routes using spring context based on examples from
here:

http://camel.apache.org/spring.html

It seems that it is not possible to use SPeL in certain fields, for example
I try to specify uri as follows:

<camelContext xmlns="http://camel.apache.org/schema/spring">
<route id="inside">
<from uri="#{ 'direct:inside' + uniqueNumber }"/>
...
</route>
</camelContext>

SPeL in the uri field is never executed and is used as is. Would it be
possible to allow for it?

Ivan.
