[FR] `xr`/`xr-hyper` support for `ltproperties`

[gusbrs]

Brief outline of the enhancement

This is just a suggestion / feature request. It would be really nice to have xr/xr-hyper support for ltproperties, so that \new@label@record data could be imported from an external document, with a corresponding url/file property.

Minimal example showing the current behaviour

File A.tex:

\RequirePackage{latexbug}
\documentclass{article}

\begin{document}

\section{Section 1}
\label{foolabel}
\RecordProperties{ltp:foolabel}{label,page}

\end{document}

File B.tex:

\RequirePackage{latexbug}
\documentclass{article}

\usepackage{xr}
\externaldocument[A-]{A}

\begin{document}

\ref{A-foolabel}

\RefProperty{A-ltp:foolabel}{label}

\end{document}

Produces:

In other words, \ref works for a label from the external document, while \RefProperty is not able to access the external document's label data.

Minimal example showing the desired new behaviour

Well, it would be nice if it worked. For both xr and xr-hyper + hyperref.

xr-hyper already support this. xr will support is once we merge both.

The packages has been merged and with the next release both packages will support ltproperties.
