XML 1.0 SE Conformance Error

Amaya has an XML parsing issue that causes it to not report an error 
that should be reported in order to be conformant

 From XML spec:
[Definition: *Validating processors* must, at user option, report 
violations of the constraints expressed by the declarations in the DTD 
<http://www.w3.org/TR/REC-xml#dt-doctype>, and failures to fulfill the 
validity constraints given in this specification.] To accomplish this, 
validating XML processors must read and process the entire DTD and all 
external parsed entities referenced in the document..

By that definition (if Amaya uses a validating XML processor), it must 
report if whitespace appears before the XML declaration.

[1]    |document|    ::=    |prolog 
<http://www.w3.org/TR/REC-xml#NT-prolog> element 
<http://www.w3.org/TR/REC-xml#NT-element> Misc 
<http://www.w3.org/TR/REC-xml#NT-Misc>*|

[22]    |prolog|    ::=    |XMLDecl 
<http://www.w3.org/TR/REC-xml#NT-XMLDecl>?Misc 
<http://www.w3.org/TR/REC-xml#NT-Misc>* (doctypedecl 
<http://www.w3.org/TR/REC-xml#NT-doctypedecl> Misc 
<http://www.w3.org/TR/REC-xml#NT-Misc>*)?|
[23]    |XMLDecl|    ::=    |'<?xml' VersionInfo 
<http://www.w3.org/TR/REC-xml#NT-VersionInfo> EncodingDecl 
<http://www.w3.org/TR/REC-xml#NT-EncodingDecl>? SDDecl 
<http://www.w3.org/TR/REC-xml#NT-SDDecl>? S 
<http://www.w3.org/TR/REC-xml#NT-S>? '?>'|

Notice that according to the above excerpts, there can be no whitespace before an XML declaration.

To reproduce:
1. Create an XHTML document.
2. Edit it in source view to add a space before <?xml.

Actual Results:
The document is parsed as if that constraint was not there.

Expected Results:
A message similar to the following should be given:
XML Parsing Error: xml processing instruction not at start of external entity
Location: file:///F:/Documents%20and%20Settings/Brant%20Gurganus/My%20Documents/Personal/brant.xhtml
Line Number 1, Column 2: <?xml version="1.0" encoding="UTF-8"?>
                       -^

Please not that the above sample is from Mozilla which is not a validating processor and by the definition of such is not required to check for this.
