Documentation for this format
Base StructureDefinition for RatioRange Type: A range of ratios expressed as a low and
high numerator and a denominator.
The stated low and high value are assumed to have arbitrarily high precision when it comes
to determining which values are in the range. I.e. 1.99 is not in the range 2 -> 3.
One of lowNumerator or highNumerator and denominator SHALL be present, or all are absent.
If all are absent, there SHALL be some extension present
((lowNumerator.exists() or highNumerator.exists()) and denominator.exists()) or (lowNumerator.empty(
) and highNumerator.empty() and denominator.empty() and extension.exists())
(count(f:numerator) = count(f:denominator)) and ((count(f:numerator) > 0) or (count(f:extension)
> 0))
not(exists(f:lowNumerator/f:value/@value)) or not(exists(f:highNumerator/f:value/@value))
or (number(f:lowNumerator/f:value/@value) <= number(f:highNumerator/f:value/@value))
IVL<RTO<QTY[not(type="TS")]>> [lowClosed="true" and highClosed="
;true"]or URG<<RTO<QTY[not(type="TS")]>>
Unique id for the element within a resource (for internal references). This may be any
string value that does not contain spaces.
May be used to represent additional information that is not part of the basic definition
of the element. To make the use of extensions safe and manageable, there is a strict set
of governance applied to the definition and use of extensions. Though any implementer
can define an extension, there is a set of requirements that SHALL be met as part of the
definition of the extension.
There can be no stigma associated with the use of extensions by any application, project,
or standard - regardless of the institution or jurisdiction that uses or defines the extensions.
The use of extensions is what allows the FHIR specification to retain a core level of
simplicity for everyone.
The stated low and high value are assumed to have arbitrarily high precision when it comes
to determining which values are in the range. I.e. 1.99 is not in the range 2 -> 3.
not(exists(f:lowNumerator/f:value/@value)) or not(exists(f:highNumerator/f:value/@value))
or (number(f:lowNumerator/f:value/@value) <= number(f:highNumerator/f:value/@value))
One of lowNumerator or highNumerator and denominator SHALL be present, or all are absent.
If all are absent, there SHALL be some extension present
((lowNumerator.exists() or highNumerator.exists()) and denominator.exists()) or (lowNumerator.empty(
) and highNumerator.empty() and denominator.empty() and extension.exists())
(count(f:numerator) = count(f:denominator)) and ((count(f:numerator) > 0) or (count(f:extension)
> 0))
