The exclude-result-prefixes attribute in both XSLT 1.0 and XSLT 2.0 allows for the exclusion of certain namespace declarations in the output document. The content assistance populates a list of available namespaces that have been defined in the stylseheet and provides them as proposals as shown in Figure 2, “Exclude-result-prefixes Content Assistance ” .

Figure 2. Exclude-result-prefixes Content Assistance

If the attribute has no values defined, then the #all value will be available in the list. If #all is already in the attributes value, then no content assistance will be available.

Figure 3. Filtered exclude-result-prefixes proposals

Content assistance is intelligent enough to know when a namespace prefix is already in the list of excluded namespaces. In this case it will not show the namespace in the proposal list.
