Junctions

Archi stores AND/OR Junction identity using a native type attribute that is separate from the element’s xsi:type.

For a Junction, the parser exposes both the interpreted semantic value and the original native value:

type ArchiJunctionType = 'And' | 'Or';

interface ArchiElement {
  junctionType: ArchiJunctionType | null;
  rawJunctionType: string | null;
}

Decoding rules

Native Junction type	junctionType	rawJunctionType
absent	'And'	''
""	'And'	''
"or"	'Or'	'or'
any other value	null	original value

These match Archi’s own IJunction constants (AND_JUNCTION_TYPE = "", OR_JUNCTION_TYPE = "or"), confirmed against Archi’s source.

Never guessed

Unknown native values are never guessed or discarded:

• parseArchiModel still succeeds — the model parses normally;
• rawJunctionType always keeps the original value, understood or not;
• validateArchiModel reports unrecognized-junction-type for a Junction whose native value cannot be resolved.

Non-Junction elements

For every non-Junction element both fields are null:

junctionType === null
rawJunctionType === null
