fontspec declaration failing with xetex unless Extension= key is used #504
Description
Description
Specified syntax should work on all engines that can be used with fontspec
Check/indicate

Minimal example demonstrating the issue
\documentclass{article}
\pagestyle{empty}
\setcounter{page}{6}
\setlength\textwidth{111.0pt}
\setlength\parindent{10pt}
%StartShownPreambleCommands
\usepackage{fontspec}
\setmainfont{Alegreya}
[ UprightFont = *-Medium.otf,
ItalicFont = *-MediumItalic.otf,
BoldFont = *-ExtraBold.otf,
BoldItalicFont = *-ExtraBoldItalic.otf]
%StopShownPreambleCommands
\begin{document}
This \textbf{text} is typeset in the \emph{family} Alegreya. It
supports \textbf{\itshape bold italic} and \textsc{Small Caps}.
\end{document}
Further details
This example from TLC3 works with LuaTeX but fails to find the OTF fonts with XeTeX. To make it work with XeTeX one has to specify
\setmainfont{Alegreya}[
Extension = .otf,
UprightFont = *-Medium,
ItalicFont = *-MediumItalic,
BoldFont = *-ExtraBold,
BoldItalicFont = *-ExtraBoldItalic
]
instead. This is unfortunate, because in theory different fonts could be in different formats (and per documentation the above syntax should work).
