i am testing a WS that adds events for an user. the last event added has an userEventId incremented, so i don't know in advance its value. to recover it, i use a Property Transfer.

Now, i would like to use an xquery match assertion to test my value. But i don't know how to use my property in the equery expression.

this matches:

```
//events[last()]/userEventId = <userEventId>12</userEventId>

```

returns: 

```
<xml-fragment>true</xml-fragment>

```

but this not:

```
//events[last()]/userEventId = <userEventId>${UserEventId}</userEventId>

```

returns: 

```
<xml-fragment>false</xml-fragment>

```

Is there a solution?
