Project to increase consistency & quality of FHIR-authored implementation guides (Jira PSS-1807)

Work groups and accelerators are now creating a significant volume of FHIR implementation guides. The templates and tooling are also increasingly being used by organizations, SDOs and other stakeholders outside HL7 international. These guides have largely migrated to using a common publishing template, however there are still significant variations in how implementation guides are organized and presented. As well, the common templates will need to continue to evolve to support new requirements and to improve implementation guide authoring, presentation, navigation, usability and accessibility for different audiences/consumers. This may involve configuration/variation for different types of guides.
