Labels and Cross-references

Slightly modified \xlabel{...} is used in place of \label{...} with the same functionality. In the same vein, \xref{...} takes the role of \ref{...}. The cross-ref command, \xref{...} accepts more than one label as its argument and the output will be sorted and compressed if needed.

As you’re aware, two TEX runs are needed to fix cross-references to newly inserted objects correctly.

Cross-ref commands:

\xref{clm1} ⟹ Claim 3.2 [Default string + counter]
\xref{clm1,clm2} ⟹ Claims 3.2 and 3.3 [Default string + counters]
\xref{clm3,clm2,clm4} ⟹ Claims 3.2—3.4 [Default string + counters, sorted and compressed]
\nxref{clm1} ⟹ 3.2 [Only counter]
\xref[env=Postulate]{clm1} ⟹ Postulate 3.2 [Custom string + counter]

A command to avoid sorting citations in a particular `\xref` command:

\xref[nosort]{label1,label2}

Global commands:

\norefsort ⟹ Do not sort the ref values in the document.
\refsort ⟹ Sort the ref values in the document (default).

Cross-ref Options

id=<id> ⟹ Add custom id (applicable only during XML generation).
num=<number> ⟹ Add custom number instead of default counter.
env=<env string> ⟹ Add custom environment string.
nolink ⟹ Remove link.
noenv ⟹ Remove string.
noctr ⟹ Remove counter.
sort ⟹ Sort the values in current xref command alone (in a non-sorted surrounding).
nosort ⟹ Do not sort the values in current xref command alone (in a sorted surrounding).
sfx ⟹ Add suffix to the counter.
pfx ⟹ Add prefix to the counter.
linkstr={<link string>} ⟹ Change default string in a multi-label \xref{...} command. Default is and, at times, users might need to change it to through and the like.
range ⟹ Provides range of references if labels for begin and end refs are provided, separated by comma.
