When precincts depend on ancillary files, there is one node under <PREC_NAME-anc> for each ancillary file needed by the precinct. Rather that referring directly to the ancillary file, the votes file refers to an alias which in turn refers to the ancillary file. This system allows us to update the version of the ancillary file just by changing the alias, without having to change the vote file. Likewise, if several configurations refer to the same ancillary file by alias, then updating the alias to point to a newer version of the ancillary will be picked up by all the configurations without the need for any further changes.
The XML syntax for ancillary file references is:
<Ancillary_File_Type>Alias</Ancillary_File_Type>
