The id is required but did not completely solve the problem:
----------------------------------------
<!DOCTYPE webpage PUBLIC "-//Norman Walsh//DTD Website Full V2.6//EN"
"file:///usr/local/docbook-website/schema/dtd/website-full.dtd"
[
<!ENTITY % sharedEntities SYSTEM
"file:///_srcBase_/foo/website/foo.ent">
%sharedEntities;
]>
---------------------------------------
fails with error 128 while
---------------------------------------
<!DOCTYPE webpage PUBLIC "-//Norman Walsh//DTD Website Full V2.6//EN"
"file:///usr/local/docbook-website/schema/dtd/website-full.dtd">
-------------------------------------
transforms without error.
Note _srcBase_ is defined in a global catalog as
------------------------------------------------------------------------------
<rewriteSystem
systemIdStartString="file:///_srcBase_/"
rewritePrefix="file:///home/foo/docbook/" />
----------------------------------------------------------------------------------
and is resloved prior to
------------------------------------------------------------------------------
<nextCatalog catalog="catalog.xml"
xml:base="file:///usr/local/docbook-website/" />
----------------------------------------------------------------------------------
Works fine with both docbook.xsl and chunk.xsl
Would appear the autolayout stylesheet may not like Entity declarations ...
