Snapshot of not well-formed API response.
It has elements with the name "Nova_Resource:Tools/Access_Request/Marian_520219" which xmllint rejects with "parser error : error parsing attribute name". This stems from the slashes ("/") in the element name which aren't allowed in XML names (cf. http://www.w3.org/TR/REC-xml/#NT-NameStartChar).
After escaping those, xmllint still complains about the perceived, but undeclared XML namespace "Nova_Resource".
The result is attached as the query is volatile.
