Add plural to newdualentry from LaTeX/Glossary

This works for me (However, a 7-arg command is difficult to remember!):

\documentclass{article}


\usepackage{xparse}

\usepackage[acronym]{glossaries}


\DeclareDocumentCommand{\newdualentry}{O{}D<>{}m m m m m } {
  \newglossaryentry{gls-#3}{
    name={#5},
    text={#5\glsadd{gls-#3}},
    description={#6},
    plural={#7},
    #1
  }
  \newacronym[see={[Glossary:]{gls-#3}},#2]{#3}{#4}{#5\glsadd{gls-#3}}
}

\makeglossaries




\newdualentry{LED}{LED}{LED}{Light emitting diode}{LEDiodes}

\newdualentry{Ox}{Ox}{Ox}{male cow}{Oxen}


\begin{document}

Here is an entry: \gls{gls-LED} \glspl{gls-LED}

An some biology here: \gls{gls-Ox} \glspl{gls-Ox}

\printglossary[type=main]
\printglossary[type=acronym]

\end{document}

Edit Some notes on the design of the command about the optional arguments:

Say,you've got a small document like this

\documentclass{article}

\usepackage{xparse}

\DeclareDocumentCommand{\somecmd}{O{}O{}m}{%
Optional 1: #1

Optional 2: #2

mandatory: #3
}

\begin{document}

\somecmd[A][B]{C}

\somecmd[A]{C}

\somecmd[][B]{C}



\end{document}

1. The first call will assign A, B and C correctly to the relevant slots
2. The second call will use A for the 1st, C for the 3rd one --> the 2nd one is empty --> Is this correct? Yes and no, since it's not clear that A is meant for the 1st or the 2nd optional argument.
3. This call will explicitly leave the 1st one empty, the others are 'correct'

It's better to replace the 2nd optional argument style with D<>{} or similar tokens to make some difference. Or append the 2nd optional argument to the end of the list, being the 3rd argument here.
