When the [xmlSchema:valueError] Element img attribute width type token value error his indicates that there is an fault in the xHTML export from Tangelo.
What is it?
The example below dictates that there is a fault within the xml (xmlSchema), it expects a certain value but that value (valueError) is incorrect. The fault is within an image (img). It explains that an image has an attribute that is 140px.
[xmlSchema:valueError] Element img attribute width type token value error: 140px, pattern facet \d+%?$|\d*\.\d+%?$|\d*\*$
In this case there was a mistake in the xHTML export. The below value is incorrect, the px should not be there. A simple case of programmer mistake.
How to fix it?
This is mostly not a user issue to solve. Please contact Tangelo Support with this error. In most cases it is a very easy fix. This can also occur when the customer can add certain width as a free field to images. In that case go through these fields and check that they are filled in correctly according the syntax provided.
