I added a new .xml file to my Resources/pages folder.
Filename is called publication.xml

I added my properties and the unique key. But I can't see the
name in the dropdown where i can choose the type of a new entry.

I tried to clear the cache already.
What am I doing wrong?

Here is the content of my publication.xml (closing template-Tag stripped by the editor here on stackoverflow?! It's there in my code)

```
<?xml version="1.0" ?>
<template xmlns="http://schemas.sulu.io/template/template"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://schemas.sulu.io/template/template http://schemas.sulu.io/template/template-1.0.xsd">

<key>publication</key>

<view>ClientWebsiteBundle:templates:default</view>
