correction language intent

Section 1.4  will be updated as follows to clarify that the intent is not to minimize integration but rather to minimize the burden of implementation as follows: The CMS Interoperability and Patient Access Rule (CMS-9115-F) specified FHIR technical standards and implementation guides that support development and testing of FHIR APIs to foster interoperability. CMS identified technical standards for Provider Directories and recommended the DaVinci PDEX Plan Net Provider Directory Implementation Guide. As healthcare providers and payers seek to incorporate social determinants of health screening assessments and referrals to social care agencies into their care management processes, we chose an approach intended to help minimize the effort/burden to implement FHIR-based human and social services directories into their workflow practices by those have already implemented the CMS-recognized FHIR standard for accessing healthcare provider directories, the  DaVinci PDEX Plan-Net Provider Directory Implementation Guide (PDEX) version 1.1.0. This section will also enhance the section describing relationship between the IGs: the PDEX Plan-Net Provider Directory, the FAST National Directory Endpoint Query Exchange IG, and the FHIR IG for Human Services Directories.
