Gets the value of the id property.

<p>
This accessor method returns a reference to the live list,
not a snapshot. Therefore any modification you make to the
returned list will be present inside the JAXB object.
This is why there is not a <CODE>set</CODE> method for the id property.

<p>
For example, to add a new item, do as follows:
<pre>
getID().add(newItem);
</pre>


<p>
Objects of the following type(s) are allowed in the list
{@link CitationType.ID }
