R4B: MolecularSequence.referenceSeq.windowStart (new:integer)
This extension is part of the cross-version definitions generated to enable use of the
element MolecularSequence.referenceSeq.windowStart as defined in FHIR R4B
in FHIR R5.
The source element is defined as:
MolecularSequence.referenceSeq.windowStart 0..1 integer
Following are the generation technical comments:
Element MolecularSequence.referenceSeq.windowStart has a context of MolecularSequence.relative based on following the parent source element upwards and mapping to MolecularSequence.
Element MolecularSequence.referenceSeq.windowStart has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element).
Context of Use
This extension may be used on the following element(s)
MolecularSequence.relative
This extension is allowed for use with FHIR versions R5 to R5 .
