Public bug reported:

In the list instance usage audit logs XML response, the element <10-150-10-15>  in <log></log>  is against the XML schema.
http://www.w3schools.com/xml/xml_elements.asp
XML Naming Rules
XML elements must follow these naming rules:

Names can contain letters, numbers, and other characters
Names cannot start with a number or punctuation character
Names cannot start with the letters xml (or XML, or Xml, etc)
Names cannot contain spaces

So if the hostname of the instance begin with number, punctuation character, etc,  the list usage audio logs response will be against the rule. 
We either don't use host name as the element name or add a prefix before the host name for the tag.
