%Schema.xmlns.attrib;

Schema Namespace Declaration

Provides an attribute-like definition (name, declared value, and default value) for the W3C XML Schema namespace used with the @xsi_schemaLocation attribute

Remarks

Namespace pseudo-attributes make the connection between a namespace prefix and a URI. In the MathML Tag Set, the parameter entity %Schema.prefix; names the prefix; thus, the attribute-name-like construction “xmlns:%Schema.prefix;” resolves to “xmlns:xsi”. The %Schema.xmlns.attrib; parameter entity then sets the value of this pseudo-attribute prefix to a URI. This Tag Set overrides the MathML (%mathml-qname.mod;) module’s declaration to set the URI as a FIXED value with the %Schema.xmlns; parameter entity naming the W3C XML Schema Recommendation (http://www.w3.org/2001/XMLSchema-instance).
