  - head
```
public MapItem head()
             throws XPathException
```
    Description copied from interface: Sequence
    
    Get the first item in the sequence.
    
    Specified by:
    
    head in interface Sequence
    
    Returns:
    
    the first item in the sequence if there is one, or null if the sequence is empty
    
    Throws:
    
    XPathException - in the situation where the sequence is evaluated lazily, and evaluation of the first item causes a dynamic error.
  - iterate
```
public SequenceIterator iterate()
                         throws XPathException
```
    Description copied from interface: Sequence
    
    Get a SequenceIterator over all the items in the sequence
    
    Specified by:
    
    iterate in interface Sequence
    
    Returns:
    
    an iterator (specifically, a Saxon SequenceIterator, which is not a Iterator) over all the items
    
    Throws:
    
    XPathException - in the situation where the sequence is evaluated lazily, and constructing an iterator over the items causes a dynamic error.
