Hello all,

I have finished my action item ACTION-288 on XPath 1.0 expressions, see the
attached zip file. Below are some comments, including questions - please
check. I cannot commit to the server at the moment - Thierry, could you do
that for me? See the attached zip file.

- I used relative location paths
http://www.w3.org/TR/xpath/#NT-RelativeLocationPath . Often it is not clear
what the starting point for the expressions is (document root or somewhere
else?), so using the relative location path seems save to me.

- I used single quotes for values, e.g. @DESCRIPTION='Image Creator'

- I kept capitalization "as is", e.g.
owners, please check whether that is appropriate.

- I used small letter "or" as a separator between xpath expressions, since
the literal sequence "or" is part of xpath spec
same for "and" http://www.w3.org/TR/xpath/#NT-AndExpr

- I replaced "AND" in examples like


with "or" since "or" is inclusive in XPath, and I think that is the desired

- EBUCore and TVA: could someone tell me the namespace URIs? The mapping
tables just mention the prefixes.

- I could (again in EBUCore) not make sense of expressions like
EBUCoreMain/coreMetadata/type/objectType/@typeLabel (collection, string)
EBUCoreMain/coreMetadata/type/objectType/@typeLink (collection, anyURI)
and I just deleted the part in the brackets ().

Regards, Felix.
