7. Data Frame Definitions
Data frames defined in this standard shall consist of the following data frames. Each shall be further
divided into specific elements as defined in this clause. Typically, these entries shall be made up of
message content internal to this document (made up of DEs that are either atomic or complex) and message
content external to this document (from other functional areas and companion volumes). Definitions for
these entries are presented in the following subclauses.
The productions of ASN.1 which follows shall be considered normative in nature. While the majority of
the normative content is reflected in the actual syntax of the ASN.1 some entries also have additional
statements in the ASN.1 comments which shall be considered to be normative as well. In addition, the
commentary provided with each entry may also provide additional normative restrictions on the proper use
of the entry which shall be followed. The XML productions follow directly from the ASN.1 specifications
and the same rules shall be applied.
7.1 Data Frame: DF_ITIS_EventType
Use: The summary data structure of all ITIS codes which can be used to form event categories. Taken
from the larger set of complete ITIS codes. A code which identifies the type of event. This is taken from
the 40-odd sub ranges of ITIS codes, and often used as a way to provide a top level sorting of the event
type. Note that the XML formation provides an outer tag which denotes the category from which the inner
element phrase was taken, this is in contrast to the more common way of using the phrases inside the
<ITIS> tag. Note the exact spelling of the tags!
