Line 36:
An advantage of EXI over Fast Infoset is that EXI (optionally) uses more constraints from the [[XML schema]]. This can make the EXI data more compact; for example, if the XML schema specifies that elements named 'bar' may only exist within elements named 'foo', EXI can assign a shorter token to the 'bar' element, knowing that it doesn't have to share the same token space as elements that occur elsewhere in the document.
The main disadvantage to utilizing such "schema-informed" compression is that, not only does the document require a schema, but the decoder needs a copy of the same schema that the encoder used.
