The reported content is limited to 4 KiB per file. If the content is valid
XML, the '<file>' node contains an attribute 'xml="yes"' indicating that
the XML information is inserted as is. Otherwise, the content is sanitized.
Furthermore, a query can contain a 'size="yes"' attribute. If set, the size of
each queried file is reported as number of bytes through an attribute 'size' in
the corresponding '<file>' node.
