ISX Interchange Syntax Extension
To allow the interchange sender to specify additional information required for the interchange receiver to perform syntax interpretation of the interchange. This segment allows specification of a release character, character encoding, and similar capabilities.

Type is not applicable; the release character prevents the character
immediately following its appearance from being treated as a Syntax Object.
Identifies a scheme for representing a set of graphical characters with bit
patterns.
Codes (16)
This code indicates the version, release, and subrelease of the value as agreed
to by trading partners to override what is in the first six characters in GS08.
Used only when code in GS07 is "X."
Overriding code reference applies to interchange content.
Value must be a published ASC X12 version/release/subrelease of an X12
standard.
When an ISX03 value is received in an interchange, all code value validation
for code values defined by the X12 base Standard will be made against the X12
version conveyed by this element. This value overrides, for code value
validation only, the first six characters of GS08 when GS07 equals "X." This
applies to any functional groups contained within the interchange, and does not
override the transaction set, loop, segment, or data element attributes.
In order to use ISX03, the sender must have explicit agreement of the receiver.
Codes (100)
An industry or trading partner identifier for an implementation guide. This is
the type of content as characters 7 through 12 of GS08. For example, VICS or
X231.
C0403: If ISX-04 is present, then ISX-03 is required
When an ISX04 value is received in an interchange, all code value validation
for code values defined by the X12 Standard will be made against the
implementation guide conveyed by this element. ISX04 constrains the full set of
codes from the X12 standard specified in ISX03.
