Yes, it's probably better to use "/*" than ".". Also, I just remembered
that the select expression uses the primary input document as context
(doh!), I should've tested it before replying the first time.
Try this pipeline:
<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="
http://www.w3.org/ns/xproc-step" version="1.0" xml:base="
http://example.net/script.xpl">
<p:input port="source">
<p:inline xml:base="file:/tmp/some-input-document.xml">
<c:result/>
</p:inline>
</p:input>
<p:output port="result"/>
<!-- the default context for the select attribute is the primary input
document -->
<p:add-attribute match="/*"
attribute-name="base-uri-from-primary-input">
<p:with-option name="attribute-value" select="base-uri(/*)"/>
</p:add-attribute>
<!-- inline documents defaults to the same base URI as the current
XProc document -->
<p:add-attribute match="/*"
attribute-name="base-uri-from-inline-document">
<p:with-option name="attribute-value" select="base-uri(/*)">
<p:inline>
<irrelevant/>
</p:inline>
</p:with-option>
</p:add-attribute>
</p:declare-step>
It will give you this:
<c:result xmlns:c="http://www.w3.org/ns/xproc-step"
base-uri-from-primary-input="file:/tmp/some-input-document.xml"
base-uri-from-inline-document="http://example.net/script.xpl"/>
Note how you need to provide a inline document to be able to access the
base URI of the xproc document. You will often need to refer to the xproc
documents base URI several times, so it might be a good idea to store it in
a variable at the beginning of the pipeline like this:
<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="
http://www.w3.org/ns/xproc-step" version="1.0" xml:base="
http://example.net/script.xpl">
<p:input port="source">
<p:inline xml:base="file:/tmp/some-input-document.xml">
<c:result/>
</p:inline>
</p:input>
<p:output port="result"/>
<p:variable name="base-uri" select="base-uri(/*)">
<p:inline>
<irrelevant/>
</p:inline>
</p:variable>
<!-- use the variable to pass the xml:base to the step (replace
p:add-attribute with your own step) -->
<p:add-attribute match="/*" attribute-name="base-uri-from-variable">
<p:with-option name="attribute-value" select="$base-uri"/>
</p:add-attribute>
</p:declare-step>
Which gives you this:
<c:result xmlns:c="http://www.w3.org/ns/xproc-step" base-uri-from-variable="
http://example.net/script.xpl"/>
