Thank you, Knut! I will do that, but leave the issue open for further refinements.

> In a comment on DERBY-6369, Knut Anders Hatlen suggests that the topic "Parameters to
getProcedureColumns" (http://db.apache.org/derby/docs/10.10/ref/rrefpgc1.html) might be removed.
The purpose of the topics under "JDBC Reference" is to provide Derby-specific implementation
information. In this topic, however, the Derby-specific information seems to apply to other
methods as well: the information on catalogs and the information on name patterns.
> It may be that another topic in the same section, "java.sql.DatabaseMetaData.getProcedureColumns
method" (http://db.apache.org/derby/docs/10.10/ref/rrefgpc1.html), could also be removed.
Derby presumably supports other DatabaseMetaData methods that are not mentioned, such as getFunctionColumns
and, more recently, getAttributes (of UDTS) and getUDTs. Why mention this one only?
> The topic "Columns in the ResultSet returned by getProcedureColumns" (http://db.apache.org/derby/docs/10.10/ref/rrefcrsrgpc1.html)
does contain Derby-specific information, listing a couple of columns that are not listed in
the Java SE documentation on this method (see http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html).
So this topic needs to be retained.
> Some information could be added to the top-level "java.sql.DatabaseMetaData interface"
topic (http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html) about needing
to specify null for catalog columns and perhaps about using the "%" wildcard to obtain a list
of all items in a particular namePattern field.
> Let me know if these changes don't make sense.
