RE: [xliff] FW: [xliff-comment] Xliff 1.2 transitional schema validation

Hello Yves,

For our 2.0 efforts, I have scripts to parse both the documentation and the schema, to find discrepancies between them. I can’t guarantee that it will catch every problem, but it’s a useful backup to our collective diligence. Similarly, to ensure consistency the tree diagrams will be generated directly from the schema, as soon as I work out a few details.

As for the original problem report in 1.2, it is as described. The documentation for the <xliff> element says:

One or more <file> elements, followed by

Zero, one or more non-XLIFF elements.

while the schema says:

<xsd:sequence maxOccurs="unbounded">

<xsd:any maxOccurs="unbounded" minOccurs="0" namespace="##other" processContents="skip"/>

<xsd:element ref="xlf:file"/>

</xsd:sequence>

I’m not sure what the appropriate response would be. And I’m not sure what it says about current implementations that the issue is only reported now.

Regards,

Tom

Hi Tom, and other Schema experts,

I don’t think anyone has answer the question below that posted on the comments list.

Maybe that is something we need to check to make sure it does not occurs in 2.0.

Subject: [xliff-comment] Xliff 1.2 transitional schema validation behaviour with extended nodes

Hi,

While doing tests for a service we’re building for translation of xliff files, we found an strange behaviour of the xliff 1.2 transitional schema for validation using an xliff with an extended element right after the <file> one, an example:

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

<body>

<trans-unit id="1" resname="I18n and L10n">

<target>Internationalisierung und Lokalisierung</target>

</trans-unit>

</body>

</file>

<ext:custom>Extended stuff</ext:custom>

</xliff>

Above file fails validation against xliff 1.2 transitional schema with the following messages:

· From .NET code: “System.Xml.Schema.XmlSchemaValidationException: The element 'xliff' in namespace 'urn:oasis:names:tc:xliff:document:1.2' has incomplete content. List of possible elements expected: 'file' in namespace 'urn:oasis:names:tc:xliff:document:1.2' as well as any element in namespace '##other'.”

· From the XLIFFChecker tool: “[Error] 12:9 cvc-complex-type.2.4.b: The content of element 'xliff' is not complete. One of '{WC[##other:"urn:oasis:names:tc:xliff:document:1.2"], "urn:oasis:names:tc:xliff:document:1.2":file}' is expected.”

The strange thing is that if we take the same file and swap the order of the <file> and the extended elements (ie, first <ext:custom> element, then <file> one) it successfully validates according to the transitional schema, even though the element order, according to the documentation, is the opposite (ie, the element order of example above that doesn’t validate).

Apparently it seems to be a bug in the schema or a mismatch between the schema and documentation, as according to the documentation the examples above should either have opposed validation results (if order is enforced) or on the contrary both validate successfully (if order is not enforced).

PD: We got the xsd for the transitional schema from the schema section of the documentation.

PD2: We have a sample VS2010 solution with tests reproducing above scenarios, but have not attached it to avoid spamming the whole dist list; please feel free to ask for it in the event it helps clarifying.
