| SPEC-251 | Allow both pattern and interval constraint on Duration in Archetypes Affects: ADL, AOM specifications ADL now supports a constraint on durations allowing both ranges and unit types (weeks, days etc) to be expressed together, e.g.: some_duration matches {PWD/|P0W..P50W|} This is typically used for pregnancy duration constraints. |
| SPEC-256 | Correct extension_validity in UID_BASED_ID class Affects: Support IM specification The text for the has_extension function is changed to indicate that the Result is True if extension is not empty (rather than not Void). |
| SPEC-260 | Correct the regex published for the ARCHETYPE_ID type Affects: Support IM specification The proposed solution is as below, and has the following features: - the characters #, ( and ) are not allowed - no part (i.e. any section between '-' or '.' delimiters) can be only 1 character long - no name part can start with a digit - allows upper case in the alphabetic parts of the id - limiting the version part of the id to numbers (i.e. no letters) - not allowing a leading '0' in the version identifier |
| SPEC-261 | Indicate how accuracy is treated over add/subtract operations in DV_QUANTIFIED types Affects: Data Types IM specification 1. in the class DV_AMOUNT, accuracy_unknown: Boolean is added as a function, and a constant called Unknown_accuracy_value of type Integer, with value = -1 is added. The documentation is changed to indicate that a value of -1, i.e. accuracy = Unknown_accuracy means no accuracy recorded, and the accuracy_unknown function returns True. 2. The class DV_ABSOLUTE_QUANTITY also has accuracy, but defined as a reference value. The accuracy_unknown function is also implemented in this class, but returns True if accuracy = Void (i.e. null). |
| SPEC-268 | Correct missing parentheses in dADL type identifiers Affects: ADL specification The dADL grammar is corrected to allow parentheses around type names, as in the following example from the ADL specification: destinations = < ["seville"] = (TOURIST_DESTINATION) < .... > |
| SPEC-271 | Correct minor inconsistencies in ITEM_TABLE specification and example Affects: Data Structures IM The ITEM_TABLE.ith_row() function is updated to the following:
ith_row (i:Integer): CLUSTER
require i >= 1 and i <= row_count |
| SPEC-283 | Correct spelling of ELEMENT.null_flavor attribute to null_flavour Affects: Data Structures IM The null_flavor attribute in the reference model class ELEMENT is renamed to null_flavour to match the published XML-schema. |
