How is a new user supposed to know the meaning of "Transclusion"?
This should be replaced by something easier to understand such as "Template". It should also be easier to translate....
The term is used on these messages:
'visualeditor-dialog-transclusion-title' => 'Transclusion',
'visualeditor-dialogbutton-transclusion-tooltip' => 'Transclusion',
Version: unspecified
Severity: normal
