User Story

As an OSCAL developer or community member, I need to be able to rely on the OSCAL docker image to perform OSCAL devops tasks (model documentation generation, schema generation, hugo builds, etc).

Currently the OSCAL image suffers from some usability issues:

• The build script does not produce targets for arm64 (rosetta translation seems to be very slow for XSLT operations)
• The image is currently too large and too slow to build
• GitHub actions relying on the pre-built docker image will not work for forks.

The speed and size of builds must be improved enough to avoid having to host prebuilt images, or infrastructure needs to be put in place to allow forks to build the image on the fly as needed.

Goals

• Adjust the build script to build for multiple targets (arm64 is a must)
• Bring over some of the speed and size improvements from the oscal workshop image
• Improve the XSpec action to build the image as needed (for forks?)
• Investigate the creation of a second "XSLT environment" image that can be split out at a later date for the metaschema-xslt repo
