Hi,

Following DITA topic validation in oXygen XML Author reports 4 errors.

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

<topic id="topic_001" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:noNamespaceSchemaLocation="urn:oasis:names:tc:dita:xsd:topic.xsd">

  <title>Topic title #1</title>

  <body>

    <p id="p_001">ABC</p>

    <p id="p_002">DEF</p>

  </body>

  <topic id="topic_002">

    <title>Topic title #2</title>

    <body>

      <p id="p_001">ABC</p>

      <p id="p_002">DEF</p>

    </body>

  </topic>

</topic>

E [ISO Schematron] The id attribute value "p_001" is not unique within the topic that contains it.
E [ISO Schematron] The id attribute value "p_002" is not unique within the topic that contains it.
E [ISO Schematron] The id attribute value "p_001" is not unique within the topic that contains it.
E [ISO Schematron] The id attribute value "p_002" is not unique within the topic that contains it.

However DITA specification says as following:

2.1.3.4.1 ID attribute
http://docs.oasis-open.org/dita/v1.2/os ... id.html#id

Note: Thus, within a single XML document containing multiple peer or nested topics, the IDs of the non-topic elements only need to be unique within each topic without regard to the IDs of elements within any ancestor or descendant topics.

So I think the id attributes must be unique only within the each topics. Is this a correct validation result?

Hello,

The Schematron involved in examining the IDs needs access to the class attributes. Because when running a Schematron we are using Saxon 9 PE, the schema is not loaded and the class attribute values are unknown. To make it schema aware, please go to Preferences, page XML / XML Parser / Schematron and check Use Saxon EE (schema aware) for xslt2 query binding.

Best regards,
Alex

Hi Toshihiko,

We'll try to improve the behavior in a future version of Oxygen so that such errors are not reported by default to our users (without users needing to change settings).
