[Psidev-pi-dev] schema key constraint

[Martin E. <mar...@ru...>]

Hi!

The schema now contains the most important primary and foreign key constraints.
That means, id attributes must be unique within their schema hierarchy level and
..._ref attributes must point to correct and existing elements 
(identified by their id attribute).

If not, schema-validation results in an error message like (XMLSpy):
'The value "bla" matched by the <keyref> identity constraint "bla2"
was not matched by the referenced key "bla3" within the scope of element <AnalysisXML>.'

I tried to make "bla2" following a simple nomenclature, e.g.
FK_DATAADSILSIR_SD

Meaning: SpectraData_ref (SD) attribute 
of element DataCollection(DATA)/AnalysisData(AD)/SpectrumIdentificationList(SIL)/SpectrumIdentificationResult(SIR)
must point to a SpectraData element.

XMLSpy jumps to the wrong reference, so human parsing
of the FK_guru_meditation is normally not necessary...

  Bye
