XML Profile - Import URL

In the Configuring security for XML content section of the Protecting XML applications chapter of the ASM config guide.

it says "If you selected a referenced file type, in the Import URL field, type the URL defined in the schemaLocation directive."

This is from the v11 manual, but the setting is still there in v13.

Basic settings do not appear to be covered in later manuals; just the advanced Web Services Security Configuration settings and Defense configuration settings under XML firewall configuration.
