GSA adds "domestic partner" to definition of immediate family

I got the below today from Federal GLOBE:

The General Services Administraiton is amending the Federal Travel Regulation (FTR) by adding terms and definitions for "Dependent," "Domestic partner," and "Domestic partnership," and by revising the definition of "Immediate family" to include "Domestic partner" and children, dependent parents, and dependent brothers and sisters of the Domestic partner as named members of the employee’s household. This interim rule also adds references to domestic partners and committed relationships, where applicable, in the FTR.

It was proposed on November 2nd and comment period ends December 20th. The effective date will be March 3, 2011.
