[xep-support] Adobe SVG

You should store the DTD referenced from your SVG file locally,
and point to it in the catalog file:

<public publicId="-//W3C//DTD SVG 1.0//EN" 
   uri="file:/C:/SVG/DTD/svg10.dtd"/> <!-- put your local name here -->

The DTD itself can be retrieved from the location contained in the
system ID that Adobe Illustrator stores inside the image:

http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd

Good Day,

I am using XML catalogs.  However, what DTD would I use in this case?

Regards,

James

Greetings,

Couldn't he just download the DTD, place it the same directory as his SVG
files, and change the DOCTYPE declaration?

Thank You,
Mike Grimley

You probably mean that you are unable to render these SVGs on a computer
that has no Internet access. This may happen because of the DTD reference:
by the XML spec, the XML parser has to access the DTD in order to resolve
entities. 

If you are using XEP for Java, then the most straightforward method of
resolving the issue consist in leveraging XML catalogs. You can read about
it in XEP User Guide:

http://xep.xattic.com/xep/doc/userguide.html#URI_Resolution

Alternatively, you could simply postprocess the resulting SVG, e.g.
by applying an XSLT identity transformation to them. This would remove all
remote DTD references, and resolve all entities.
Please note that you will need to add catalog support to the XSLT processor
if you want this process to be performed without network access; this is
processor-dependent, so please refer to the documentation of your XSLT
processor.

The rest of your entities are just namespace URIs. They never get resolved,
and should not pose any problem.
