The src for the frame content. The src is modified in several ways to make things much easier to work with.
A nested <ao:src> tag will override this value.

In order to simplify things behind URL mapping schemes, the src 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.
