[jira] [Commented] (FOP-2520) Empty elements consume space

["Jan Tosovsky (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FOP-2520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14711161#comment-14711161 ] 

Jan Tosovsky commented on FOP-2520:
-----------------------------------

Have you formatted the code above? There is white space between multiple <fo:wrapper> elements which seems to be preserved which is IMO correct. Multliple indexterms in Docbook source shouldn't be delimited with anything (but some editors like XMetal do this, so extra post processing - space removal, is required). For XEP the generated XSL-FO source differs as there are custom XEP tags instead.

> If you use {{indexterm}} tags in DocBook, the DocBook XSL stylesheets generate empty {{fo:wrapper}} or {{fo:block}} elements with an {{id}} attribute. These elements take up visible space if processed with FOP. Using XEP, those empty tags do not consume any space.

> <fo:block space-before.optimum="0.6em" space-before.minimum="0.4em" space-before.maximum="0.8em">
