<DL>
<DD>Creates a Reader for a raw InputStream.
 <p>
 It follows the same logic used for files.
 <p>
 If lenient detection is indicated and the detection above fails as per specifications it then attempts
 the following:
 <p>
 If the content type was 'text/html' it replaces it with 'text/xml' and tries the detection again.
 <p>
 Else if the XML prolog had a charset encoding that encoding is used.
 <p>
 Else if the content type had a charset encoding that encoding is used.
 <p>
 Else 'UTF-8' is used.
 <p>
 If lenient detection is indicated an XmlReaderException is never thrown.

<DL>
<DD>Creates a Reader using the InputStream of a URL.
 <p>
 If the URL is not of type HTTP and there is not 'content-type' header in the fetched
 data it uses the same logic used for Files.
 <p>
 If the URL is a HTTP Url or there is a 'content-type' header in the fetched
 data it uses the same logic used for an InputStream with content-type.

<DL>
<DD>Creates a Reader using an InputStream an the associated content-type header.

 First it checks if the stream has BOM. If there is not BOM checks the content-type encoding.
 If there is not content-type encoding checks the XML prolog encoding. If there is not XML
 prolog encoding uses the default encoding mandated by the content-type MIME type.
