Code the tags and keywords exactly as they are shown in the text. The tags and keywords are represented like this:
:tagname.keyword() keyword()

In tag descriptions, a vertical bar in each pair of keywords or values indicates that you must include one of the pair with the tag. For example, the syntax for the PROPERTY tag includes the NULLS keyword values NULLS(Y|N). You must code either NULLS(Y) or NULLS(N).
