Thanks Heikki - appreciate the detailed feedback - I'll include it in the review.

Subject: Re: [GeoNetwork-users] [GeoNetwork-devel] HELP NEEDED.. additional metadata elements in GN (how to describe them).. hi Tania, Simon, if your schema is named iso19139.yourprofilename, then it is assumed in the code that it is an extension of iso19139, is what I think. This means that many of the XSLTs just use the templates in the XSLTs in the iso19139 schema present directory, unless you override them. Simon please correct me if I'm wrong here .. >for example written on page 26 - Creating the extract XSLTs - its written we must create four xslts, but there is only three examples (extract-date-modified.xsl, extract-gml.xsl, and extract-uuid.xsl). You can just copy the same 4 xslts from the iso19139 schema and not modify them unless that's needed for your profile. >Also there is an example of the eml-gbif schema (p.31) and there was nothing written about eml-gbif schema before, which got me lost. Yes, it may be a bit unclear that in the middle of explaining about the mcp profile, the doc starts referring to other profiles as well. Probably to illustrate some points that could not be illustrated with the mcp profile. In any case, like Simon said, check out the schemaprofiles SVN directory, for several examples including that one. Some remarks about the documentation from my experience: (1) if you just create the profile in the /schemas directory with the intention of having it automatically loaded on startup, you need to include it too in WEB-INF/schemaplugin-uri-catalog.xml. Don't think this is documented and took me awhile to discover. (2) what's not clear to me is what forms of detection you can put in schema-ident.xml -- don't think all the mechanism is documented, there are just some examples in the schemaprofiles SVN. For example can I detect a schema by the simple presence of a particular namespace declaration in the root element ? And what if several schemas match, how is it decided which one wins ? (3) the doc describes first one method of doing it, and then shows another way of doing it. This is a bit disconcerting if you follow the doc as a step-by-step guide. Maybe it's better to introduce in the beginning the two methods with links to them; or just describe only one of them, certainly if one method is preferred over the other. If I think of anything else, I'll add to this thread.
