Not sure what you are asking. The parser does not care if the first step is a spine reference or not, for instance to parse

Code:

epubcfi(/4[idParaDest-e]/2/4[toc])

you simply call parse_epubcfi()

which will give you:

Code:

({u'steps': [{u'id': u'idParaDest-e', u'num': 4},
   {u'num': 2},
   {u'id': u'toc', u'num': 4}]},
 {},
 {},
 u'')

read the steps from the first returned value.
