This is the namespace document for the POWDER XML schema. It defines a set of high level IRI constraints for Internet-based IRIs.

This namespace document describes the POWDER XML schema, which extends and re-defines the POWDER-BASE XML schema [POWDER-BASE], by defining a set of high level IRI constraints, for Internet-based IRI, denoted by the fact that they all include a host component (such as IRIs with schemes http and ftp).

More precisely, it defines a new set of child elements of powder:iriset , plus an element, namely abouthosts , which is used instead of the powder:aboutregex element defined in POWDER-BASE.

This type re-defines the structure of the powder:iriset element, by defining a set of elements, expressing high level constraints on IRIs.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the scheme component starts with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the scheme component does not start with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the host component ends with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the scheme component does not end with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the port component matches string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the port component does not match string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component matches string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component does not match string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component contains string S 1 OR … OR string S n . This element can occur 0 or more times as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component does not contain string S 1 OR … OR string S n . This element can occur 0 or more times as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component starts with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component does not starts with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component ends with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the path component does not end with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a string S, denoting the set of IRIs where the query component contains string S. This element can occur 0 or more times as a child of the powder:iriset element.

This element takes as value a string S, denoting the set of IRIs where the query component does not contain string S. This element can occur 0 or more times as a child of the powder:iriset element.

This element takes as value an IRI pattern, specified according to the syntax of an access item, as defined in [AC], denoting the set of IRIs matching that pattern. This element can occur at most one time as a child of the powder:iriset element.

I'm not sure this should be part of POWDER. Maybe, it is preferable to define it in a separate schema.

This element takes as value an IRI pattern, specified according to the syntax of an access item, as defined in [AC], denoting the set of IRIs which do not match that pattern. This element can occur at most 1 time as a child of the powder:iriset element.

I'm not sure this should be part of POWDER. Maybe, it is preferable to define it in a separate schema.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs matching string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs which do not match string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:iriset element.

This type defines the structure of the includequerycontains and excludequerycontains elements, which consists of a string of type powder:iriQuery , and an optional attribute delimiter , denoting the character used to separate parameter-value pairs in the IRI query string. The default value for such attribute is &.

This attribute is used to denote the character delimiting parameter-value pairs in elements includequerycontains and excludequerycontains .

This element takes as value a space-separated list of strings S 1 … S n , denoting the set of IRIs where the host component ends with string S 1 OR … OR string S n . This element can occur at most one time as a child of the powder:attribution element.
