Communication specifications define structures designed to meet particular requirements. For example, recording a decision to prescribe a particular pharmaceutical product or substance might trigger an electronic prescription sent to the pharmacy. Reference sets may also be used to specify the allowed values in messages and for constraining the codable elements in data entry models. For some bindings it may be relevant to apply certain conditions, to enable that one value set is displayed given a specified criteria, and another value set is displayed given another criteria (or set of criterions). An example of such conditional value set binding

Footnote Macro

Value set bindings are used to express the valid values used to populate an information model artifact. For example the value set used to populate a drop down menu in a user interface or the valid values for a coded text in a message model.

Query specification reference setQuery specification reference sets may be used to represent a set of intensionally defined SNOMED CT subsets, where each subset represents the value set for a particular field in a communication messages. One query specification reference set may therefore be used to hold all value sets applicable within a single communication messages, or within a set of messages.
