Add helper functions to check if an attribute is
mandatory, immutable or unique in the class definition.
ex: for a host widget component, these are defined
as follows:
attributes {
#
# host objects instantiated within the same alsaconf node must have unique
# direction attribute
#
unique "direction"
mandatory [
"type"
"stream_name"
]
immutable [
"uuid"
]
}
