The address of a person or organisation. It can contain electronic components such as E-Mail or URLs.
The XADDR can contain XVARs which give the components of the address. A Number of these are BUILTINs and can be picked from the list in tecml-var.ent. These include:
Note that URLs and EMAILs are specific TYPEs for XVAR and this is the best way of using them (SGML forbids them also to be used as BUILTINs).
An optional/repeatable list of XVARs carrying either BUILTIN information or specific to the application. Note that E-mail addresses and URLs are already catered for as TYPEs in XVARs so do not need BUILTIN.
