RE: why not in p:exec ... ""If cwd is not specified, the cwd is the same as the xproc file one is running."?

Location and PWD are different.

Simple case, suppose the xproc "file" was served via a URL 

                http://www.mine.com/xproc.xml

 

Then you can do a URI resolution to find an associated xslt file

http://www.mine.com/xslt.xsl

 

But "http://www.mine.com" cant serve as a CWD.

 

Similar cases for OS's without CWD's but with filenames.

 

In cases where the xproc file was made in memory then it would have been up
to the environment to supply the 'base URI' which may or may not be a
"directory" in a 'filesystem'.

 

exec CWD's and URI's are different.

 

You can see a rant on a similar problem in xmlsh

Thanks for the simpler way and the explanation, although other steps seem to
rely on a concept of cwd being the directory the xproc file is in for
example xslt files are referenced as relative to the location of the xproc
file so I'm not clear on the reasons p:exec would differ from those and a
bit interested to know why as I assume there is a reason.

An expression like: resolve-uri('./', $lib-base-uri) gives you the directory
with an ending slash.

 

But David makes sensible remarks. It could well be that even this approach
does not return a useful uri..

Yes, those are the sorts of reasons that the WG didn't attempt to specify
the CWD.
