Re: own defined step and xml:base "inheritance"

You could resolve the URI each time you invoke your step:

<p:import href="common.xpl"/>
<p:pipeline type="igs:xml2ecf" xml:base="file:///C:/foo/bar/">
    <igs:xslt>
        <p:with-option name="href"
select="resolve-uri('xsl/igs/v2.5/main_igs_v2.5.xsl', base-uri(.))"/>
    </igs:xslt>
</p:pipeline>

Alternatively, you could add a base-uri option to your step:

<p:import href="common.xpl"/>
<p:pipeline type="igs:xml2ecf" xml:base="file:///C:/foo/bar/">
    <igs:xslt href="xsl/igs/v2.5/main_igs_v2.5.xsl">
        <p:with-option name="base-uri" select="base-uri(.)"/>
    </igs:xslt>
</p:pipeline>

The base URI of p:with-option in your last example is (almost certainly) an
absolute file URI pointing to the file you declared igs:xslt in. The
xml:base is not "inherited" in any way, and there's no "tunneling"
mechanism that could be used like there is in XSLT (although I wish there
were).

Hope this helps.
