 ### Data graph binding
 
-`<shacl-form>` requires only a shapes graph as input via the attribute `data-shapes` (or `data-shapes-url`) to generate an empty form and create new RDF data from the form input fields. Using the attributes `data-values` (or `data-values-url`) and `data-value-subject`, you can also bind an existing data graph to the form. The given data graph is then used to fill the form input fields.
