Verify that an svg file is compliant with the RFC standards.

Project description

Check SVG against RFC schema

This program takes an XML file containing an SVG or an RFC document. It then compares all of the SVG elements with the schema defined in the document with RFC 7996 bis. The program has the option of modifying and writing out a version of the input that passes the defined schema.

The RFC Editor is in the process of changing the canonical input format of Internet-Draft and RFC docuemnts. As part of this process, the ability to create artwork which is not ASCII text is being introduced. This is being done with SVG. However, the full set of SVG does not match with the archival nature of RFCs so a subset of the SVG specification is being defined by the RFC Editor that eliminates many capabilities such as animation. Additionally, there is a requirement that the images have the widest possible usage both by printers, monochrome displays and individuals with visual disabilities. Further information on the process can be found on the RFC Editor at the RFC Editor site.


svgcheck accepts a single XML document as input and optionally outputs a modified version of the document.

Basic Usage: svgcheck [options] SOURCE


The following parameters affect how svgcheck behaves, however none are required.

Short Long Description
-C --clear-cache purge the cache and exit
-h --help show the help message and exit
-N --no-network don’t use the network to resolve references
-q --quiet dont print anything
-r --repair repair the SVG so it meets RFC 7966
-v --verbose print extra information
-V --version display the version number and exit
-X --no-xinclude don’t resolve xi:include elements
-d RNG --rng=RNG specify an alternate RNG file
-o FILENAME --out=FILENAME specify an output filename


svgcheck depends on the following packages:


Version 0.5.16 (Mon 1 July)

  • Require new version of rfctools for new RNG file

Version 0.5.15 (Mon 27 May)

  • Fix errors where we need to emit UTF-8 characters in either text or attributes
  • Add test case for UTF-8
  • Force DOCTYPE not to be emitted when we have fixed a file so that we don’t pick up default attributes
  • Add test case for two pass

Version 0.5.14 (Sun 21 Apr)

  • Force a viewBox to be part of the output
