Section 3.22 URLs and External References¶
<url> tag always requires an
@href attribute. Usually this will be some external web page, or other resource. If the
<url> is empty, then the value of the
@href attribute will be the link text, typically in a monospace font. You can also provide your own content, using elements much like any other piece of text that would occur in a paragraph. Of course, there is no need to anticipate any problems with LaTeX output and special characters like a tilde. Use the character itself in the
@href, and use the
<tilde> element in the content (or wrap the content in the
<c> element and use the literal character).
This element may also be used to link to external data files. See Section 6.19 for details.
