Renders an <area> tag.
The body is invoked to support nested tags, but with any output discarded.
Any attribute that has no namespace and begins with

coerced to String
for the parameter value.

The href for the area. The href is modified in several ways to make things much easier to work with.
A nested <ao:href> tag will override this value.
In order to keep paths app-relative, if starts with a /, the context path will be prepended to the path.
In order to simplify things behind URL mapping schemes, the href is always written starting with '/'. This avoids any need to include any <ao:base> tags.
URL rewriting is performed as needed via HttpServletResponse.encodeURL.
To support paths in different character sets, a Unicode to ASCII URI encoding is performed on every character that is not defined in RFC 3986: Reserved Characters. To avoid ambiguity, any dynamic parameters or anchors in the URL must have been correctly encoded by the caller.
If the href represents a local resource, a parameter of "lastModified=#####" may be
automatically added with the timestamp of the local resource to the nearest second.
