DOCBOOK-APPS: Non SGML Character Number?

[Holger Rauch <Holger.Rauch@heitec.de>]

Hi!

I'm suddenly having trouble parsing German XML documents. When using PSGML
mode in Emacs and parsing my DocBook XML V4.1.2 document, I get numerous
messages of the form:

	nsgmls:DecisionBrowser.xml:109:15:E: non SGML character number 129

If I substitute my umlauts by ae, oe, or ue, respectively, this error goes
away. The document in question is an article having lang="de" as an
attribute.

My XML declaration is specified as follows:

	<?xml version="1.0" encoding="iso-8859-1" standalone="no"?>

My SGML_CATALOG_FILES variable contains (the newline characters are just
here for readability):

/usr/share/sgml/CATALOG.docbk30:/usr/share/sgml/CATALOG.docbk31:
/usr/share/sgml/CATALOG.gnome:/usr/share/sgml/CATALOG.iso-ent:
/usr/share/sgml/CATALOG.tei-3:/usr/share/sgml/CATALOG.tei-3.system:
/usr/share/sgml/CATALOG.teixlite:/usr/share/sgml/jade_dsl/catalog:
/usr/share/sgml/openjade/catalog:/usr/local/docbook/dtds/sgml/4.1/docbook.cat:
/usr/local/docbook/dtds/xml/4.1.2/docbook.cat:
/usr/local/docbook/style/dsssl/1.70/catalog

What's going on here?

Thanks in advance for any help!

Greetings,
