Schema documentation for component diggs:statistic

How several values are reduced to the single value compared against
the limit. statisticScope states what the values are gathered over.
Omit where the criterion applies to each value individually. Values
come from the enumerated list, or "Other: xx", where xx is a
user-defined term whose meaning differs from every listed value (not
a synonym of one).

90 for a 90th-percentile criterion. Give it only with that
statistic.

What the statistic is gathered over: the values within one record
(series), the evidence for one subject (evidence), or all subjects
the criterion governs (population). Required whenever statistic is
given. Values come from the enumerated list.

enumeration

series

The values within one record - for example the largest settlement in one
monitoring record, or the slope of one load-test curve.

enumeration

evidence

The evidence for one subject - for example the mean of the cylinders taken
from one grout batch.

enumeration

population

All subjects the criterion governs - for example 95% of the columns in a
zone, or a testing frequency across a program.

The comparison applied between the evaluated value and the limit.
Required: a limit without a comparison states no requirement. Values
come from the enumerated list.

content	simple
minOccurs	1
maxOccurs	1

enumeration

Less than or equal to the limit's value.

enumeration

Greater than or equal to the limit's value.

enumeration

Strictly less than the limit's value.

enumeration

Strictly greater than the limit's value.

enumeration

Equal to the limit's value.

enumeration

Not equal to the limit's value.

enumeration

within

Within an inclusive range. Use with a limit that populates parameterMinValue
and parameterMaxValue rather than parameterValue - this is the operator that
carries a tolerance band such as "0.25 to 0.75 in".

The subject this criterion governs, and the value or range the
evaluated value is compared against. The subject is the
dictionary-bound parameterName of a diggs:AuthorizedParameter or
diggs:ProvenancedParameter; a free-text diggs:Parameter is not
allowed. The value may be a single value (parameterValue) or a band
(parameterMinValue and parameterMaxValue, with operator "within").

The unit of work the criterion is assessed over, for example per
element, per unit cell, per 100 ft, or as a multiple of diameter.
Distinct from the scope of the specification, which says which
features are governed. Use the DIGGS dictionary basis.xml for the
list of values.

A condition evidence must meet to count toward this criterion: a
coded parameter and its value or range, for example specimen age 28
d, elapsed time 1 to 10 min, or depth below the platform. Evidence
counts only if it meets every condition given. Omit where all
evidence of the criterion's subject counts.

Abstract base type for acceptance criteria: which evidence counts, how it is reduced
to one value (statistic over statisticScope), the comparison (operator) and the
limit. The subject is named by the parameterName of limit. The criterion names no
evidence of its own; the evidence it is evaluated against is cited by the
diggs:AcceptanceCheck that applies it.

gml:id

required

Database handle for the object. It is of XML type ID, so is constrained to be
unique in the XML document within which it occurs. An external identifier for the object in
the form of a URI may be constructed using standard XML and XPointer methods. This is done
by concatenating the URI for the document, a fragment separator, and the value of the id
attribute.
