It appears that some of the Xpress control parameters are not currently supported in MOI_wrapper.jl. It would be nice to have access to these parameters via the JuMP interface. For example:

ERROR: LoadError: KeyError: key "MAXMEMORYSOFT" not found
Stacktrace:
 [1] getindex(::Dict{String,Any}, ::String) at ./dict.jl:477
 [2] set(::Xpress.Optimizer, ::MathOptInterface.RawParameter, ::Int64) at /home/deploy/.julia/packages/Xpress/weWYC/src/MOI/MOI_wrapper.jl:459
 [3] Xpress.Optimizer(; kwargs::Base.Iterators.Pairs{Symbol,Int64,NTuple{5,Symbol},NamedTuple{(:MAXTIME, :OUTPUTLOG, :RESOURCESTRATEGY, :MAXMEMORYSOFT, :TREEMEMORYLIMIT),NTuple{5,Int64}}}) at /home/deploy/.julia/packages/Xpress/weWYC/src/MOI/MOI_wrapper.jl:248

You can get the definition from the C header file and append to: https://github.com/jump-dev/Xpress.jl/blob/master/src/common.jl
