Hey Alex,
This looks really promising!
When I run validate with this schematron I get the following:
System ID: C:\svn\scripts\svgCheck.sch
Engine name: ISO Schematron (XSLT 2.0)
Severity: fatal
Type: XML validation
Start location: 149:0 (Odd because the schematron is only 14 lines)
System ID: C:\dita\pt\products\vitek2systems\pi\Appendix_A.dita (This is the first file with an SVG for the document I checked.)
Engine name: ISO Schematron (XSLT 2.0)
Severity: error
Description: Exception thrown by extension function {public static boolean com.saxonica.functions.extfn.EXPathFile.exists(java.lang.String)}: java.lang.NullPointerException
Type: XML validation
Even if I delete all SVG references, I receive the above two errors.
I then tried it on a map with more SVGs and some that were verified to be broken. It is properly detecting the errors but I see false positives when the SVG contains embedded images instead of linked. I believe it’s trying to verify the binary data as the uri.
System ID: C:\dita\en\products\simon\service\Attachments.dita
Engine name: ISO Schematron (XSLT 2.0)
Severity: error
Description: A sequence of more than one item is not allowed as the first argument of resolve-uri() ("data:image/jpeg;base64,/9j/4AA...", "data:image/png;base64,iVBORw0K...")
Type: XML validation
Is there a way for me to adjust the schematron to ignore href values that start with “data”?
I had previously attended a webinar Oxygen presented on schematron. I’m finally starting to understand how powerful it can be!
Thank you,
Matt

Hello Matt,
In Oxygen v15.0 we've added in the "Validate and check for Completeness" dialog a new entry called "Additional schematron checks" in which you can specify additional Schematron checks that should be be executed on the topics. You can perform the check you've described using a Schematron file with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<schema
xmlns="http://purl.oclc.org/dsdl/schematron"
queryBinding="xslt2"
xmlns:exslt="http://expath.org/ns/file">
<ns uri="http://expath.org/ns/file" prefix="exslt"/>
<pattern>
<rule context="image[ends-with(@href, '.svg')]">
<let name="svgDocument" value="document(@href)" />
<assert test="exslt:exists(resolve-uri($svgDocument//*:image/@*:href, base-uri($svgDocument)))">
The image file from the following SVG doesn't exist: <value-of select="base-uri($svgDocument)"/></assert>
</rule>
</pattern>
</schema>
Best regards,
Alex

Hey Guys,
This is a feature request that's not extremely crucial, but it would be helpful for us.
I'm having our authors create SVG overlays and link to the background image (jpeg or png).
Sometimes they accidentally link to an image that isn't in our repository path.
Within the SVG, I'll end up with something like:
<image width="1200" height="1807" xlink:href="../../../../../../../Users/Username/Pictures/PREVI PAV/PAV_printer_cover_open.jpg" >
When it should be:
<image width="1200" height="1807" xlink:href="images/PAV_printer_cover_open.jpg" >
Although, the validate/check for completeness wouldn't catch this on their workstation as the image exists and is valid, it would find it quickly on mine since it's outside the path that gets checked in and I’d be missing that image.
It doesn't seem like the OT throws any errors either. The only way I find out is when I'm viewing the PDF and notice that antenna house has substituted a broken image.
Example:
Thanks!
