Question

I have the the grammar of a xml element defined by

<xsd:element name="valid" type="xsd:duration"/>

but in the xml I want to specify an infinite duration. How can i specify infinite duration?

I checked http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#duration but I could not find a way to specify unlimited duration.

You must define the maximum for your application. XSLT engines may support different maximums, but it is up to you to define it using maxInclusive.

<xsd:restriction base="xsd:duration">
  <xsd:maxInclusive value="P3M" />
</xsd:restriction>
