The spectrumRef holds the value of the id attrubute of the spectrum from which the precursor ion was selected. An ordered list of these precursors can be given; the referred-to id numbers my not represent spectra present in the mzData file, but this should not present a bar to providing the history of this scan. Example (trivially); MS survey scan has id = 1 and the first MSMS spectrum has id= 2, with the spectrumRef attribute on precursor for the MSMS spectrum having the value 1.</xs:documentation>
