Incorrect documentation

Security experts,

  The official Java Security Standard Algorithm Names incorrectly documents the Signature.*withECDSAinP1363Format algorithms as

SEQUENCE ::= { r INTEGER, s INTEGER }

This is incorrect. The IEEE P1363 Format is defined as concatenating the r and s values (with no ASN.1 encoding, but with appropriate padding). The implementations appear correct. This just appears to be a documentation issue.  The documentation for Java 11, 12, and 13 would need to be updated.

I refer you to the Wikipedia page [2], item #7 that has the relevant information



Thank you.
