Here's a fairly minimal example showing an issue, using ConTeXt LMTX. Save the following as "main.tex": % SOF \startbuffer[document] <body><img src="circle.svg"/></body> \stopbuffer \startbuffer[csvg] <svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg"> <g><circle cx="50" cy="50" r="20"/></g> </svg> \stopbuffer \startxmlsetups xml:xhtml \xmlsetsetup{\xmldocument}{body|img}{xml:*} \stopxmlsetups \startxmlsetups xml:body \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:img \placefigure{}{\externalfigure[\xmlatt{#1}{src}][conversion=mp]} \placefigure{}{\externalfigure[circle.svg][conversion=mp]} \placefigure{}{\includesvgbuffer[csvg][conversion=mp]} \stopxmlsetups \xmlregistersetup{xml:xhtml} \starttext \xmlprocessbuffer{xhtml}{document}{} \placefigure{}{\externalfigure[circle.svg][conversion=mp]} \placefigure{}{\externalfigure[diagram.svg][conversion=mp]} \stoptext % EOF Save the contents of "\startbuffer[csvg]" to a file named "circle.svg", to create a valid, external SVG file. Copy "circle.svg" to a file named "diagram.svg" to create a second valid, external SVG file. Run: context main.tex Expected All the SVG images appear. Actual Figures 1, 2, and 4 show only the following text: \includesvgfile[circle.svg]\resetbuffer[svg-circle-inclusion] In contrast, consider the following document: % SOF \startbuffer[csvg] <svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg"> <g><circle cx="50" cy="50" r="20"/></g> </svg> \stopbuffer \starttext \placefigure{}{\includesvgbuffer[csvg][conversion=mp]} \placefigure{}{\externalfigure[circle.svg][conversion=mp]} \placefigure{}{\externalfigure[diagram.svg][conversion=mp]} \stoptext % EOF All the images appear as expected. Any idea why using XML setups appears to affect the behaviour of rendering SVG documents using MetaPost? Thank you!

It has to do with catcodes, chicken and eggs.

Thanks, Hans. The image is now rendered. Here's a picture of the output from ConTeXt (left) and the expected output using Apache Batik: https://i.ibb.co/zPqfhjK/metapost-svg.png Would a copy of the SVG file be useful for unit testing? Thanks again.
