Status: RESOLVED DUPLICATE of bug 307813

(Core :: SVG, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Xml document with correct svg image content type (image/svg+xml) is displayed as svg vector image only when svg root element has namespace attribute set: xmlns="http://www.w3.org/2000/svg"
If this attribute is ommited, then Firefox 1.5 Beta 2 displays it as a plain XML

MS IE or any Firefox 1.x with adobe svgviewer plugin displays in both cases rendered image. Opera 8.5 also displays it correctly as an image.

For example:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="300" height="300" version="1.1" xmlns="http://www.w3.org/2000/svg">
 <rect width="300" height="100" style="fill:rgb(0,0,255);stroke-width:1; stroke:rgb(0,0,0)"/>
</svg>
is displayed correctly as an image (filled rectangle)

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="300" height="300" version="1.1">
 <rect width="300" height="100" style="fill:rgb(0,0,255);stroke-width:1; stroke:rgb(0,0,0)"/>
</svg>
is displayed as xml document (although content type is correctly recognized as image/svg+xml)

Reproducible: Always

Steps to Reproduce:
1. Create svg file (for example rect.svg) with content
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="300" height="300" version="1.1" xmlns="http://www.w3.org/2000/svg">
 <rect width="300" height="100" style="fill:rgb(0,0,255);stroke-width:1; stroke:rgb(0,0,0)"/>
</svg>
2. In Firefox 1.5 open it as a file, or place it to some web server
3. 

Actual Results:  
Source XML document is displayed. (incorrect)
Content type is recognized as image/svg+xml. (correct0

Expected Results:  
Rendered svg image (for example filled rectangle)

It seems that svg is recognized from presence of xmlns="http://www.w3.org/2000/svg".
IMHO content type should be used instead (or in combination).
It seems that Adobe Svg Viewer plugins and Opera 8.5 use content type, while they display the same result regardles of xmlns attribute presence.

This is an SVG problem, Core->SVG

It is also a duplicate of bug #307813
