The example QTI item sample doesn't pass the schema definition

[lakuri]

The sample provided on the github repository fails the schema validation. This is because there is a MimeTypeDType validation on the type attribute of qti-stylesheet .
The regular expression being used is [\p{IsBasicLatin}-[()<>@,;:\\"/\[\]?=]]+/[\p{IsBasicLatin}-[()<>@,;:\\"/\[\]?=]]+
I tried by updating the regex formula and then validating XML. That validates the XML successfully.

Sample item : https://github.com/1EdTech/qti-examples/blob/master/qtiv3-examples/packaging/BBQsTest/id-be3cd3bdd3d4/order-mountains.xml
Specified schema definition: https://purl.imsglobal.org/spec/qti/v3p0/schema/xsd/imsqti_asiv3p0_v1p0.xsd
Failing xml:
<qti-stylesheet href="flickrMash.css" type="text/css"/>

Is the regular expression wrong or am I missing something?

Steps to reproduce:

• Open the item xml file (file should contain the qti-stylesheet element) Eg; https://github.com/1EdTech/qti-examples/blob/master/qtiv3-examples/packaging/BBQsTest/id-be3cd3bdd3d4/order-mountains.xml
• Validate the XML using a plugin
• A validation message is displayed

That's interesting.

I don't have a validation problem when I validate with a schema-validating tool like Saxon, or with the built-in Eclipse XML validator.

What is the "plugin" that you are using? Is it XMLSpy? If not, I wonder if XMLSpy throws a validation error on this.

There are additional examples of the use of <qti-stylesheet ... type="text/css" /> in QTI Conformance and I've never encountered this problem (again, using Saxon or Eclipse), so I don't know what to make of this.

FYI. I was able to validate this xml file successfully using XMLSpy Professional 2020 for Windows:

That regexp uses character subtraction which a lot of regexp libraries don't support. That might explain why it woks in some tools and not in others.
It might be useful to see if the regexp could be rewritten to not make use of character subtraction.
