[oXygen-user] Trouble validating SVG document

[Reaves, Timothy]

I have an SVG document where the openeing SVG element is:
<svg  version="1.0" xmlns:x="&ns_extend;" xmlns:i="&ns_ai;"
xmlns:graph="&ns_graphs;" xmlns="&ns_svg;" xmlns:xlink="&ns_xlink;"
     width="497.611" height="591.554" viewBox="0 0 497.611 591.554"
     style="overflow:visible;enable-background:new 0 0 497.611 591.554;"
xml:space="preserve">


Validation fails on each of the xmlns attributes.  This should be valid.
The errors look like:
SystemID: /home/bv6679/Development/images/HSVG/99571_97YA_17.svg
Engine name: Xerces
Severity: error
Description: Attribute "xmlns:x" must be declared for element type "svg".
Start location: 29:21
End location: 29:42

Any ideas?
