MEG 0024

MISMO Engineering Guideline (MEG) 24, which outlines the MISMO architecture development and interoperability principles for XML technologies and service requirements as identified by the MISMO constituency. MEG 24 was approved as final in June of 2023.

MISMO MEGs are created to ensure that MISMO work products adhere to all applicable technology standards, are produced in a consistent fashion, and meet the needs of the mortgage industry.

This MEG provides guidance on when to use elements and when to use attributes. The Version 3.x XML schemas are unique and designed to be element-centric, as the data being communicated is carried at the element level as opposed to the attribute level. The containers are also defined at the element level, known as complex elements. Both types follow rules as defined in MEG-0040. In addition, there is information that is carried at the attribute level for any element.
