The change traces to RC3 issue "Fixed and variable-length String versus non-character data" that was accepted prior to moving the project to GitHub. That enhancement expanded string and data types to:
- Fixed-length character array - primitive type of an element is char
- Variable-length character string - element is char
- Fixed-length opaque data - element is an octect, also known as byte, specified as uint8
- Variable-length opaque data - element is octet
In sum, text fields can be fixed or variable-length and data can be fixed or variable-length. The difference between them is that text fields are subject to a character set (US-ASCII is the default character set in FIX) while opaque data has no internal structure known to the message encoding.

Thank you, Don!
Could you confirm that both Int and char as primitive types of data should be working fine for RC2 implementations?
from fix-simple-binary-encoding.
The RC2 schema is available here Simple Binary Encoding - Release Candidate 2 - XML Schema (XSD)
These are the enumerated primitive types:
<xs:restriction base="xs:token">
<xs:enumeration value="char"/>
<xs:enumeration value="int8"/>
<xs:enumeration value="int16"/>
<xs:enumeration value="int32"/>
<xs:enumeration value="int64"/>
<xs:enumeration value="uint8"/>
<xs:enumeration value="uint16"/>
<xs:enumeration value="uint32"/>
<xs:enumeration value="uint64"/>
<xs:enumeration value="float"/>
<xs:enumeration value="double"/>
</xs:restriction>
