Removing SECTIONINFO from Docbook document processing

Hello
all, 

I have a basic DocBook XSL question. I want to include
<sectioninfo> in the large sections and it will carry information about
who wrote it, when, etc. 

I do NOT want any off this it to show up in my documents
[PDF & HTML]. 

What kind of a template can I include in my XSL
stylesheet that ignores this and any children in that section in the output,
but still validates it for future use?
