How to enable (for example) Greek character entities in db5?

[Johan Persson <johanp@aditus.nu>]

I'm trying to understand jpw to include some greek characters in a docbook v5 article but I fail to understand how to enable the "Greek Letters Character Entities".

The docbook guide says to specify the "Greek Letters Character Entities" (%isogrk1;)

Q1: Where/how should this parameter be specified so I can reference the Greek character as entities in the text?

If I read the XSL guide it says - and I quote:

>The DocBook DTD defines the character entities that make it easy to add
>special characters to your XML files. To enter a copyright symbol, for
>example, it is easier to remember a name like &copy; than the equivalent
>&#x00A9; Unicode entity.
>
>Depending on the source for your DTD download, the files that
>define the character entity names may not be included. They are on the OASIS
>website under http://www.oasis-open.org/docbook/xmlcharent/index.shtml. Create
>a directory named ent in the directory where the DocBook DTD files are, and
>extract the entity files into ent. The DTD will find them in that location
>because it has references that look like "ent/iso-amsa.ent"."

But I still fail to understand how I can instruct (for example) "xsltproc" to recognize these additional entities. Even using the "raw" unicode fails since
xsltporc interprets that as an entity (i.e. &#0903;) Since ENTITY is not really cosher in db5 the above explanation does not seem to apply anyway.

Can someone shine some light on the errors of my way here ?
