How to read step files with external references

Such as title.
I fond the description in "STEPCAFControl_Reader.hxx" is that "This reader supports reading files with external references".
But i can't find the method to read files with external references.
Help!

I find the solution. Before reading assembly structure step file, we must read the part step files.

LoadStep: TCVS1_v002/_TCVS1_handle.stp

LoadStep: TCVS1_v002/_TCVS1_rod.stp

LoadStep: TCVS1_v002/_TCVS1_handle.stp //This and all above files are part step files.

LoadStep: TCVS1_v002/TCVS1_v002.stp //This is assembly structure step file
