When describing the difference between MB and PDC datasets, the 2.6 spec says:
“For PDC, a group in the assembly that is […] a softlink represents a dataset index associated to its parent node.”
I don’t understand what this means. How can a softlink represent a dataset index? Surely the softlink points to a block group that is a sibling of the Assembly group, right?
PDC require that the block groups have an integer-valued Index attribute. Are these arbitrary, sequentially numbered from 0 in the order the groups are created in the file, or something else? There’s no indication of how they are used.
