I'm sorry but I don't know. XMLmind XML Editor uses the Xerces XML
parser bundled with our product through the standard Java XML APIs (JAXP).

That's right, it deletes it when you save the file to disk, but this
cannot be considered to be a flaw.

You are 100% right. We forgot to test this.
Yes, Xerces Java 2.9.1 ignores the UTF-8 BOM! The XML declaration has
priority over the UTF-8 BOM.
The attached XML file, which corresponds to the test you have described,
opens fine in XMLmind XML Editor.

"The UTF-8 BOM should make that the XML encoding declaration is ignored"
is not something clearly stated in the XML 1.0 spec.
<?xml version="1.0" encoding="ISO-8859-1"?>
