Altova Stylevision 2011 inserting ​ zero width space blocks

Question

Using an old 2011 version of Altova StyleVision:

Editing a file definition, I export the document to XSL-FO and get inline zero width spaces added that were not in the previous version of the file.

<fo:inline-container>
    <fo:block>
        <xsl:text>&#x200B;</xsl:text>
    </fo:block>
</fo:inline-container>

This adds extra unwanted vertical space in the generated output.

I can manually remove this ... but would like to know what causes it and how to avoid it happening in the future.

The only information I have been able to find is on the Altova Forums which states this cannot be done. I hope this is wrong.

Answer 1

Found the solution:

Set the XSL-FO Generation to "Full usage of XSL-FO standard" on the XSL Options tab of the options.
