Feature requests:  pass parameters

I would like to pass a parameter to the page to be included. e.g.:
{{page>wiki:pages:test?value=Test&noheader}}
like: [[wiki:pages:test?value=Test|Page]]

Here the parameter “value” should be passed to "wiki:pages:test" with the value "Test". At the Moment the ? and =  are replaced by an underscore: wiki:pages:test_value_Test.

Thank you in advance
