XML Conformance

WSF files encapsulate one or more script programs that can be run with the wscript or cscript programs. WSC files define scriptable automation (COM) objects written in a WSH-supported language. Both file types are formatted with Extensible Markup Language (XML) tags that define the structure of the program or component.

• tag and attribute names are case insensitive,

• attribute values need not be enclosed in quotes, if the value contains no spaces, and

• the <script> element is “opaque” to the parser, so script code inside the <script> element can use XML's special characters (<, >, and &) without special consideration.
