XML Attribute Name or Nmtoken

[metrologist]

I am having an XML Parser Error at line 34, char 64, Message:

Attribute 'boardno' refers to an unknown entity '1'
The value '1' for attribute 'boardno' must be Name or Nmtoken

I'm not able to get past this or understand the problem as name or Nmtoken seem to have few limitations on characters that can be used.


XML code:

Code: [Select]

<graphic boardno = "1" boardfile = "Caution.jpg"></graphic>

DTD bits:

Code: [Select]

<!ELEMENT graphic (mapref*)>
<!ATTLIST graphic
%graphicatt;
  hplace      (left | right | center | none )  #IMPLIED
  graphsty   NMTOKEN  #IMPLIED
