</pre>
<p>Publish acts on individual attributes of objects. If an object has no
attributes except <code>_id</code>, it will not be published to the
client. Generally, empty object are not very useful so this is not a
problem. If you need to create and track an object and assign it
properties later, create it with a simple property
eg: <code>collection.insert({exists: true});</code>
