Is it possible to version few selected properties of node?

Hi

I have node type with following structure.
book:file  and book:folder  extends book:node.

When I make an node as node:file , is it possible to make property of
book:node non- versionable and property of book:file as versionable.
Basically user can change name, path title ...without making versions but
when book:content is changed, node should be versioned.



[book:node] > nt:base
- book:name (string) mandatory 
- book:path (string)  
- book:title (string) 
- book:nodeType (string)
- book:description (string) 
- book:reportID (string)
- book:createdDate (date)
- book:publishedDate (date)
- book:unPublishedDate (date)
- book:region (string)
- book:department (string)
- book:language (string)
- book:organizationID (string)
- book:keywords (string)
- book:securityRoles (string)multiple

[book:file] >  book:node
- book:content (binary)  
- book:contentTxt (string) 


[book:folder] >  book:node
+ * = book:file multiple

Thanks
