Properly escape "<" and ">" in api-doc documentation.
Since all documentation is rendered via HTML, the characters "<" and ">" have to be HTML-quoted, otherwise strange things (omission, unintended renderings) might occur.
E.g. the sentence
Define an interface between a page and an ADP <include> similar to the page_contract.
was rendered as
Define an interface between a page and an ADP similar to the page_contract.
Fixes for Oracle 19c: replaced "limit" by the portable idiom "fetch ... rows only"
This fixes the following bug in Oracle installations: : SQL: : select aml_email_id from acs_mail_lite_from_external : where processed_p <>'1' : and release_p <>'1' : order by priority : !>>>!limit :email_max_ct : nsoracle.c:1367:OracleSelect: error in `OCIStmtExecute ()': ORA-00933: SQL command not properly ended
