No problem: you just need to say what you want. Such an element
has a content model consisting of:
1) any number of attributes with text content and
2) any number of sub-elements with model ANY interleaved with
3) arbitrary text.
In NX syntax that would be:
ANY = attribute * {text}* &
element * {ANY}* &
text
to which we can add a concrete element for testing:
start = element catchbin {ANY}
which taken jointly translate to standard syntax thus:
<?xml version="1.0" encoding="ISO-8859-1"?>
<grammar xmlns="http://relaxng.org/ns/structure/0.9";>
<define name="ANY">
<interleave>
<zeroOrMore>
<attribute>
<anyName/>
<text/>
</attribute>
</zeroOrMore>
<zeroOrMore>
<element>
<anyName/>
<ref name="ANY"/>
</element>
</zeroOrMore>
<text/>
</interleave>
</define>
<start>
<element name="catchbin">
<ref name="ANY"/>
</element>
</start>
</grammar>
