DocBook XML is superficially compatible with DocBook SGML but has a slightly stricter DTD that we have been violating in a few cases. Although XSLT doesn't care whether the document is valid, the style sheets don't necessarily process invalid documents correctly, so we need to work toward fixing this. This first commit moves the indexterms in refentry elements to an allowed position. It has no impact on the output.

<command>MOVE</command> repositions a cursor without retrieving any data.

<command>MOVE</command> works exactly like the <command>FETCH</command>
|

command, except it only positions the cursor and does not return rows.

<para>
|
|
On successful completion, a <command>MOVE</> command returns a command
|
|
tag of the form
|
|
<screen>
|
|
MOVE <replaceable class="parameter">count</replaceable>
|
|
</screen>
|
|
The <replaceable class="parameter">count</replaceable> is the number
|
|
of rows that a <command>FETCH</command> command with the same parameters
|
|
would have returned (possibly zero).
