Description
This field supports arbitrary Perl data structures by serialising them using Storable
perl module, up to the same maximum length of Longtext fields.
When serialised into XML the values are further encoded in Base64 to avoid any problems with invalid XML character data being emitted by Storable.
This field does not support storing simple scalars, (e.g. "Hello, World!").
