+The files of the `l3kernel` bundle provide an API for TeX programmers
+with defined syntax conventions, completely separating it from document level
 syntax. Hence, the commands provided are not intended for use at the document
 level nor for use in describing design layouts in document class files.
 
-This API provides the foundation on which the LaTeX3 kernel and other advanced
-extensions are built. Special care has been taken so that they can be used
-within a LaTeX2e context as regular packages.
+This API provides the foundation on which new additions to the LaTeX kernel and

-While `l3kernel` is still experimental, the bundle is now regarded as broadly
-stable. The syntax conventions and functions provided are now ready for wider

 Requirements
 ------------
 
-The `l3kernel` bundle requires the e-TeX extensions and additional functionality
-to support string comparisons, expandable character generation with arbitrary
-category codes (for Unicode engines) and PDF support primitives (where direct
-PDF generation is used). The bundle only works with the following engines:
-* pdfTeX v1.40 or later
-* XeTeX v0.99992 or later
-* LuaTeX v1.10 or later
-* e-(u)pTeX from mid-2012 onward
+The `l3kernel` bundle requires the e-TeX extensions and a number of additional
+'utility' primitives, almost all of which were first added to pdfTeX. In
+particular, the functionality equivalent to the following pdfTeX primitives must
+be available
 
-pdfTeX v1.40 was released in 2007, and so any recent TeX distribution
-supports `l3kernel`. Both XeTeX and LuaTeX have developed more
-actively over the past few years, and for this reason only recent
-releases of these engines are supported.
+- `\ifpdfprimitive`
+- `\pdfcreationdate`
+- `\pdfelapsedtime`
+- `\pdffiledump`
+- `\pdffilemoddate`
+- `\pdffilesize`
+- `\pdflastxpos`
+- `\pdflastypos`
+- `\pdfmdfivesum`
+- `\pdfnormaldeviate`
+- `\pdfpageheight`
+- `\pdfpagewidth`
+- `\pdfprimitive`
+- `\pdfrandomseed`
+- `\pdfresettimer`
+- `\pdfsavepos`
+- `\pdfsetrandomseed`
+- `\pdfshellescape`
+- `\pdfstrcmp`
+- `\pdfuniformdeviate`
 
-(Engine developers should contact the team for detailed discussion about
-primitive requirements.)
+For ease of reference, these primitives will be referred to as the 'pdfTeX
+utilities'. With the exception of `\expanded`, these have been present in pdfTeX
+since the release of version 1.40.0 in 2007; `\expanded` was added for TeX Live
+2019. Similarly, the full set of these utility primitives has been available in
+XeTeX from the 2019 TeX Live release, and has always been available in LuaTeX
+(some by Lua emulation). The Japanese pTeX and upTeX gained all of the above
+(except `\ifincsname`) for TeX Live 2019 `\ifincsname` for TeX Live 2020.
 
+At present, the `\expanded` primitive is emulated if unavailable. This code is
+slow and imposes some coding restrictions. As such, it will be *removed* for TeX
+Live 2022.
+
+In addition to the above, engines which are fully Unicode-compatible
+must provde the functionality of the following primitives, documented in the
+LuaTeX manual
+
+- `\Uchar`
+- `\Ucharcat`
+- `\Umathcode`
+
+The existence of the primitive `\Umathcode` is used as the marker for Unicode
+support.
