I don't know if this helps, but here with xmlto 0.0.28 on Debian if I apply this the docs still build:

    diff --git a/Documentation/texi.xsl b/Documentation/texi.xsl
    index 0f8ff07eca..332a65558d 100644
    --- a/Documentation/texi.xsl
    +++ b/Documentation/texi.xsl
    @@ -7,7 +7,7 @@
     <xsl:output method="xml"
                encoding="UTF-8"
                doctype-public="-//OASIS//DTD DocBook XML V4.5//EN"
    -           doctype-system="http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd" />
    +           doctype-system="http://example.org/docbook/xml/4.5/docbookx.dtd" />

So whatever's needing to remote fetch those resources doesn't seem to cause the same error for me.
