• XML:
  ====
    - I/O avoid copies when parsing mmap'ed files, need to use
      unmutable buffers except for the last 4K to make it 0 terminated
      (or get rid of 0 termination check in the whole parser, hard !)
    - recheck > 4Gb instances for parsing, and RNG validation.
      
  
  XSLT:
  =====
    - global variable access
       for each expr in stylesheet : allocate index
       for each transformation context
         create an index table
           cache values in the transformation
  	   - context evaluation
  	     - cache
  	     - constants at the XPAth level
  	   - provide more info on compiled expressions
  	     - dependances w.r.t. variables (which ones)
  	     - dependancy on the current node
  	     - dependancy on the current document
    - do not use _private but other fields in the node structures.
