In the System.Xml.Linq API, the concatenation of the namespace and a local element name creates the expanded name. When an invalid expanded name exception is raised, it can occur when a LINQ to XML query uses an element attribute, and the attribute name that is used is an empty string.

<Items><item id=”1”>one</item><item id=”2”>two</item>
<item>three...
