+introduction: |
+  This profile release targets 64-bit application processors for markets
+  requiring a high-degree of binary compatibility between compliant implementations.
+description: |
+  This profile release is intended to be used for 64-bit application
+  processors running rich OS stacks.  Only user-mode and
+  supervisor-mode profiles are specified in this release.
+
+  NOTE: There is no machine-mode profile currently defined for this release.
+  A machine-mode profile for application processors would only be used in specifying platforms for
+  portable machine-mode software. Given the relatively low volume of
+  portable M-mode software in this domain, the wide variety of potential
+  M-mode code, and the very specific needs of each type of M-mode
+  software, we are not specifying individual M-mode ISA requirements in this release.
+
+  NOTE: Only XLEN=64 application processor profiles are currently defined.
+  It would be possible to also define very similar XLEN=32 variants.

+    introduction: |
+      The RVA23U64 profile specifies the ISA features available to user-mode
+      execution environments in 64-bit applications processors.  This is the
+      most important profile within application processors in
+      terms of the amount of software that targets this profile.
