YAML file loading gives an error. Is it possible to ignore a field

Hi,
I am trying to use YAML.jl to load an YAML file. It gives me a big error (included below). It appears (may be I am wrong about this) that it cannot understand one of fields that has value like !!set {}. Is it possible to ignore that field when loading YAML, or specify only the fields I want? Is there another workaround?

Thank you.

Some example sections from the file:

ALLCorALLD:
  inspects_source: false
  long_run_time: false
  makes_use_of: !!set {}
  manipulates_source: false
  manipulates_state: false
  memory_depth: 1
  stochastic: true
AON2:
  inspects_source: false
  long_run_time: false
  makes_use_of: !!set {}
  manipulates_source: false
  manipulates_state: false
  memory_depth: 2
  stochastic: false

The error

ERROR: set type not yet implemented at line 4, column 16
