Size (attribute of entity)
When a select box is generated on a form to establish a relationship with another entity, the options for that element are populated from the existent records of the entity. If there is a large number of records for the entity this may cause poor performance and usability issues. Using the size attribute with "large" as a value forces the service used to populate the select box to limit the number of records to the first page only.
<entity name = NAME label = LABEL size = "large"> ... </entity>
