Dot-walking provides access to fields on related tables from a form, list, or
script.

If the current table contains a reference to another table, any field on the referenced table
can be accessed using dot-walking.

Dot-walking references a field by building a chain of field names separated by dots (periods).
For instance, incident.assigned_to.company references the company of the
user assigned to an incident. The recommended limit for chain length is three levels.
