Two short examples, how \setupreferencestructureprefix and definestructureseparatorset can be used. Unfortunately without any syntax descriptions or explanations
{{todo|complete example would be better}}
==Adjusting the level of referenced prefixes==
When the default chapter and section prefixes are used, the chapters are
prefixed by a number, so are the sections. When referring to a section using
the command <cmd>in{section}[sec:foo]</cmd> the chapter number is prefixed
following by a dot and the according section number.
However, some styles do not show the chapter prefix while displaying the
sections. In this case the referencing commands, like <cmd>in</cmd> just output the
section number, which is of course ambiguous.
To fix this problem, the command <cmd>setupreferencestructureprefix</cmd> can be
incorporated to adjust the prefixes displayed by the referencing commands.
===Example===
Given that <cmd>start/stopchapter</cmd> output <tt>Romannumerals</tt> prefixes (<tt>I,
II, III, …</tt>) and <cmd>start/stopsection</cmd> output <tt>Character</tt> prefixes (<tt>A,B, C, …</tt>), the following commands give the results provided in the comments.
