Reference, but do not link

It might not have been obvious in the previous chapters, but the type option is - optional. The reason for that is that is has a default, which is plain and just means "do not link".

So we can have a reference that is no link? Yes, we can. And it makes sense in various situations.

First, the text a reference produces is the same whether we make it a link or not. And this text by default is the tag body. So

    \REF{name=There type=linked}<there>
  
    \REF{name=There type=plain}<there>

only differ in the fact that "there" is made a link in the first case, and pure text in the second.

Yes, \REF{name=There type=plain}<there> (or \REF{name=There}<there>) produces the same result as the plain, pure text there. Although this doesn't seem to make sense on first sight, it makes things consistent - it can be used the same way in all cases. Think of bodyless references:

    // use a sequence number in an image title
    Image \SEQ{name="block graph" type=images}.
  
    ...
  
    // make page number a link
    Looking at the \REF{type=linked
    name="block graph"}. image, we see
    that the block graph ...
  
    // insert the page number, but
    // without linking
    Looking at the \REF{type=plain
    name="block graph"}. image, we see
    that the block graph ...
  
    // same using default values
    Looking at the \REF{
    name="block graph"}. image, we see
    that the block graph ...

All we need to do in the last two example paragraphs is to have a number that corresponds to the sequence number, we do not need to make it a link. It's for exactly that case that plain was invented.

In the same way, references to page titles and page numbers of a reference target are often used to insert just that title or number, not a link to them.
