Add DSL for building Custom HL7 structures?

[ohr]

Although it's possible now to compile custom HL7 structures at runtime, creating these custom structures is still unintuitive. I wonder if a DSL like the one used for HL7 validation could help, e.g. compare the custom definitions in modules-hl7 (below package org.openehealth.ipf.modules.hl7.parser.groovytest.hl7v2.def.v25, way more than 100 LOC) with:

forVersion('2.5') .message('MDM', 'T01 T02') .addSegment('ZBE')

.newSegment('ZBE') .addRepeatingType('MovementId', EI, 999) .addType('StartMovementDateTime', TS, 26) .addType('EndMovementDateTime', TS, 26) .addType('Action', ST, 10)
