I get FeatureQueryResult from gpkx and I can create a FeatureColleciton Layer without problems.   The issue I have is to add more attributes to the layers, i.e. add Field to Table of featureCollection.Tables.    Is there a way to do this?    Or create a new FeatureCollectionTable from the existing one to generate a new FeatureCollectionLayer?

Fields in FeatureCollectionTable are defined by fields that are in FeatureQueryResult. There is no way to add attributes to a FeatureCollectionTable after the fact

I found a way.   You create a new FeatureCollection from the original FeatureCollection.   For each table, you replicate the existing fields and add  new Fields.   Create a new FeatureCollectionTable.   For each Feature, you add new Field attributes and add to this new FeatureCollectionTable.  Then  create FeatureCollectionLayer from this.
