MISMO Introduces Engineering Guideline to Enhance Clarity on Use of XML Attributes, Elements

MISMO, the real estate finance industry’s standards organization, announced the availability of the new 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.  

“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,” said David Coleman, President of MISMO.

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.

MISMO’s work to solve key business challenges is made possible due to lender support of the MISMO Innovation Investment Fee. For information on MISMO and how to join visit MISMO.org.
