CSS3 namespaces not working as described in documentation

[ctparker]

I'm having some issues getting CSS3 namespace selectors working in Author mode.

These are all equivalent and work as described in "Supported Features from CSS Level 3":

@namespace oxy 'http://www.oxygenxml.com/extensions/author';
@namespace oxy "http://www.oxygenxml.com/extensions/author";
@namespace oxy url(http://www.oxygenxml.com/extensions/author);
@namespace oxy url('http://www.oxygenxml.com/extensions/author');
@namespace oxy url("http://www.oxygenxml.com/extensions/author");

These do not work:

@namespace oxy 'http://www.oxygenxml.com/extensions/authorx';
@namespace oasis 'http://www.oasis-open.org/specs/tm9901.html';

Why does the URL matter? I was under the impression that it simply had to be a unique string. Are other namespaces even supported?

How do I know what the correct URL is for, say, the 'oasis' namespace?

For now, I seem to be able to get along with the "*|element" selector, but I have not been able to get a specific namespace to work, for instance: "oasis|table". Is this supported (aside from the 'oxy' namespace)?

Hello,

Please post the complete samples (XML and CSS) showing the problem. In the following you may find a working sample.

I used the Oasis namespace to define a table layout in the CSS:

Code: Select all

@namespace oasis 'http://www.oasis-open.org/specs/tm9901.html';



oasis|article{

    display:block;

}



oasis|table{

    display:table;

    border:1px solid blue;

}



oasis|tr{

    display:table-row;

}



oasis|td{

    display:table-cell;

    border:1px solid blue;

    padding:20px;

}



*|td{

    background-color:yellow;

}

The XML was:

Code: Select all

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

<?xml-stylesheet type="text/css" href="test.css"?>

<article xmlns="http://www.oasis-open.org/specs/tm9901.html">

    <table>

        <tr>

            <td>1</td>

            <td>2</td>

            <td>3</td>

        </tr>

        <tr>

            <td>2</td>

            <td>1</td>

            <td>3</td>

        </tr>

    </table>

    

    

    <!-- Table that is NOT in the Oasis namespace. -->

    <table xmlns="">

        <tr>

            <td>1</td>

            <td>2</td>

            <td>3</td>

        </tr>

        <tr>

            <td>2</td>

            <td>1</td>

            <td>3</td>

        </tr>

    </table>

    

</article>

The first "table" element was rendered as a table, while the second was displayed as a block, because the second "table" element was not in the Oasis namespace.

I hope this helps,

Dan
