Validation errors when using XmlReader on XML/SVG files with inline DTDs (Unity/Mono C#)

I am trying to read in an SVG file in C# (Unity/Mono C#) so I can extract the path elements I am interested in. I don't actually want to validate the document. I have even tried ValidationType = ValidationType.None to no avail.

I keep running into errors and I simply cannot get the file to be validated or skip validation, without modifying the SVG file which I really shouldn't be doing. I thought having a ValidationEventHandler would stop the code from blocking, but it was not so.

I have checked that the files are valid SVG/XML from the W3C validator and it came up fine.

Error:

 XmlSchemaException: XmlSchema error: Element svg is not declared.

or (When I edit the SVG and put a local file in the !DOCTYPE)

 XmlSchemaException: XmlSchema error: Attribute value is invalid against its data type 'Mono.Xml.Schema.XsdID'. 'kvg:StrokePaths_0f9ad' is an invalid NCName.

Code:

 // Set the validation settings.
 XmlReaderSettings settings = new XmlReaderSettings();
 settings.XmlResolver = null;
 settings.ValidationType = ValidationType.DTD;
 settings.ProhibitDtd = false;
 settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
 settings.IgnoreWhitespace = true;
 
 // Create the reader
 XmlReader reader = XmlReader.Create(path_to_kanji, settings);
 
 //Parse the file.
 while (reader.Read())
 {
     //Extraction of data
 }

SVG file:
