| * A block is a collection of static text and elements, and components, derived from a component template. In the |
| * template, a block is demarcated using the <t:block> or <t:parameter> elements. The interface defines no |
| * methods, but the provided implementations of Block are capable of rendering their contents on demand. |
| * <p/> |
| * Tapestry includes coercions from String to {@link org.apache.tapestry5.Renderable} and {@link |
| * org.apache.tapestry5.Renderable} to Block. This means that components that take Block parameters may be bound to |
| * literal strings, to arbitrary numbers (or other objects, with the expectation that they will be converted to |
| * strings), or to renderable objects such as components. |
