#12 XSLTHL breaks processing XML fragment (String Index out of Bounds)

[Radu Coravu]

Processing the content of the following codeblock with the XML token marker breaks the processor:

        <codeblock outputclass="language-xml">&lt;?xml version="1.0" encoding="UTF-8"?&gt;
        &lt;!DOCTYPE x:root [
            &lt;!ENTITY ent "entity"&gt;
        ]&gt;

        &lt;x:root <b>xmlns:x="nsp"</b>&gt; 
          |
        &lt;/x:root&gt;</codeblock>

Exception:

 [xslt] java.lang.StringIndexOutOfBoundsException: String index out of range: 97

Committed TC + small fix.
