There are several places in the catalogue code that
accumulate the IDs (item_id and node_id) for elements
in an instance of CrbInt32Array.
These number are intentionally 64 bit numbers in the
schema to allow for very large databases and so the
template is artifically limiting the range of values.
Need a new CrbInt64Array in /common/Utilities along
with changes in the catalogue template.
Should also check the other templates to make sure 64
bit values are correctly supported.
