DocBook: attribute 'float' not allowed here validation error

[abc]

With this code

Code: Select all

<sect3>

<title>A Title</title>

<para>Some text::</para>

<para>

  <figure id="my_id">

    <title>Figure title</title>

    <mediaobject>

      <imageobject>

        <imagedata

          fileref="images/blah.png"

        />

      </imageobject>

    </mediaobject>

  </figure></para>

</sect3>

Oxygen XML Editor 13.2, build 2012040515 is giving me the error

Code: Select all

E [Jing] attribute "float" not allowed here; expected attribute "annotations", "arch", "audience", "condition", "conformance", "dir", "floatstyle", "label", "linkend", "os", "pgwide", "remap", "revision", "revisionflag", "role", "security", "userlevel", "vendor", "version", "wordsize", "xlink:actuate", "xlink:arcrole", "xlink:href", "xlink:role", "xlink:show", "xlink:title", "xlink:type", "xml:base", "xml:id", "xml:lang" or "xreflabel"

Why am I getting that validation error? The red squiggly lines are on this line

Code: Select all

<figure id="my_id">

. I also tried adding the

Code: Select all

float

attribute like this

Code: Select all

<figure id="my_id" float="false">

which didn't change anything.

Why am I getting the "attribute "float" not allowed here" error even though I am not even using that attribute?

How am I supposed to fix that?

[abc]

Adding the "xml" prefix to the "id" didn't help either:

Code: Select all

<figure xml:id="initial_script" float="true">

Hi,

Could you post a complete XML sample? I cannot quite reproduce your problem.
Are you using Docbook 5? If so, all IDs should indeed be defined using xml:id instead of id.

I opened a regular installation of Oxygen 13.2 and tried to validate this small XML document (created from your code sample):

Code: Select all

<?xml-model href="http://docbook.org/xml/5.0/rng/docbook.rng" schematypens="http://relaxng.org/ns/structure/1.0"?>

<?xml-model href="http://docbook.org/xml/5.0/rng/docbook.rng" type="application/xml" schematypens="http://purl.oclc.org/dsdl/schematron"?>

<article xmlns="http://docbook.org/ns/docbook"

    xmlns:xlink="http://www.w3.org/1999/xlink" version="5.0">

    <info>

        <title>Article Template Title</title>

        <author>

            <orgname>Organization Name</orgname>

            <address>

                <city>City</city>

                <street>Street</street>

                <postcode>000000</postcode>

                <para>Some text::</para>

                <para>

                    <figure id="my_id">

                        <title>Figure title</title>

                        <mediaobject>

                            <imageobject>

                                <imagedata fileref="images/blah.png"/>

                            </imageobject>

                        </mediaobject>

                    </figure>

                </para>

            </sect3>

        </sect2>

    </sect1>

</article>

and validation reported a problem with the id attribute but no problem with the "float" attribute.

Thank you for your quick reply!

Here is the entire XML example. Yes, we are using DocBook 5.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<?oxygen RNGSchema="http://www.oasis-open.org/docbook/xml/5.0/rng/docbookxi.rng" type="xml"?>

<sect1 xml:id="test" xmlns="http://docbook.org/ns/docbook"

  xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xlink="http://www.w3.org/1999/xlink">

  <title>Test</title>

  <sect2>

    <title>Some title</title>

    <para>Some text:</para>

    <para>

      <figure xml:id="initial_script" float="true">

        <title>Some figure title</title>

        <mediaobject>

          <imageobject>

            <imagedata fileref="images/some_image.png"/>

          </imageobject>

        </mediaobject>

      </figure>

    </para>

  </sect2>

</sect1>

I tried your example and it works without validation error after I added the "xml" prefix to "id":

Code: Select all

<figure xml:id="my_id">

I supposed that there is a mistake with my nesting of the DocBook XML elements.. or something else. I'll try to figure it out. If you happend to see the problem, I'd be grateful for a hint.

Hi,

From the XML sample you sent you seem to be using the float attribute on the <figure> element.
If I remove that attribute from there, the XML validates.
Looking at the Docbook 5 specification for figure:

http://docbook.org/tdg5/en/html/figure.html

it seems there is no attribute called float allowed on the element but there is an attribute called floatstyle which you could probably try instead.

Radu

With your analysis, hints and link to the specification, I was able to locate and fix the problem.

Thanks a lot for your help!
