The following changes are made (note that these changes allow both non-parenthesised and parenthesised forms of dADL to exist, even in the same archetype).

In the dADL grammar rules, the following rule is updated:

type_identifier:
'(' V_TYPE_IDENTIFIER ')'
| '(' V_GENERIC_TYPE_IDENTIFIER ')'
| V_TYPE_IDENTIFIER
| V_GENERIC_TYPE_IDENTIFIER


In the cADL scanner rules, a new pattern match needs to be added in the V_C_DOMAIN_TYPE section:

-- the following version matches a type name without () and is deprecated
[A-Z]{IDCHAR}*[ \n]*< -- match a pattern like
-- 'Type_Identifier whitespace <'

-- the following version is correct ADL 1.4/ADL 1.5
\([A-Z]{IDCHAR}*\)[ \n]*< -- match a pattern like
-- '(Type_Identifier) whitespace <'

This change will mean that numerous existing archetypes containing inline dADL C_DV_QUANTITY sections would not parse, e.g. http://svn.openehr.org/knowledge/archetypes/dev/adl/openehr/ehr/entry/observation/openEHR-EHR-OBSERVATION.blood_gases.v1.html.

Tools should therefore allow the current non-parenthesised form of a typed dADL section as well as the parenthesised form required by this change. Tools that perform modifications to archetypes should silently replace the old form by the new form.
