                           CharSequence value)
```
    Put a string attribute, removing it if the string is empty (nor null).
    
    Parameters:
    
    key - key of attribute
    
    value -

```
    Representation as encoded markup attributes.
    
    Overrides:
    
    toString in class ValueMap
    
    Returns:
    
    String representation of this ValueMap consistent with the tag-attribute style of markup elements. For example: a="x" b="y" c="z".
