Schema Change Log of Changes Made for 

Green House Gas to Light Duty and Fuel Economy 

This document identifies XML schema modifications to the VERIFY Light Duty (LD) and Fuel 

Economy (FE) family of schemas to include Green House Gas (GHG) data elements. There are 2 

basic types of modifications. Modifications that involve internal file structure, having no impact 

to the logical data model, were made to bring the new schema in sync with the current schema 

development paradigm per EPA XML data standard [GD2-E]. These changes involve only the 

location and organization of the schema components that comprise the logical data model and 

some changes to data type names. No data element names were changed in this process. 

Modifications that involve the addition of new schema components to included GHG data were 

also made. Because the current schema development paradigm for certain kinds of data 

validation has moved the validation to business rules, hence making the schema much less 

susceptible to data requirement changes, new GHG data elements have more generic data types. 

Because some of the GHG data elements have been reused from the original LD schemas, these 

LD data elements now also have more generic data types. This basically relaxes the schema 

validation of the LD instances of these data elements but also requires that any business rules 

written for data validation for the GHG instances additionally be applied to the LD instances as 

well.

Note that 3 LD schemas had no GHG modifications but also underwent the modifications to bring 

the schemas in sync with the current schema development paradigm. Also, 2 new schemas were 

developed for GHG data. As such, no change log is included in this document for these 5 

schemas. Also note that modifications to annotations are not tracked.
