Thanks Brad[M], you made my day !
As mentionned by finejustice, you can find the list of ID attributes (by the way, it's Groove instead of Grove ;-) and much more at https://technet.microsoft.com/library/en-us/jj219426.aspx
I needed only Excel, Word and Powerpoint, and my configuration.xml, listed below, is OK but for OneDrive (setup.exe still installs it, so I had to remove it afterwards) :
<Configuration>
<Add SourcePath="C:\Office Professional Plus 2016" OfficeClientEdition="64" >
<Product ID="ProPlusRetail">
<Language ID="en-us" />
<ExcludeApp ID="Access" />
<ExcludeApp ID="Publisher" />
<ExcludeApp ID="Groove" />
<ExcludeApp ID="Lync" />
<ExcludeApp ID="OneDrive" />
<ExcludeApp ID="Outlook" />
<ExcludeApp ID="OneNote" />
<ExcludeApp ID="Visio" />
</Product>
</Add>
<Logging Name="OfficeSetup.txt" Path="%temp%" />
</Configuration>
