This document is available via the PhixFlow online help. A binary file grammar is an XML document that specifies the structure of a binary or ASCII file. 

Note in the following sections that:

• attribute (beginning with lower case a) refers to attributes of nodes, in the standard terminology of XML.
• Attribute Node (beginning with upper case A) refers to a node that represents a target File Collector Column– that is, an Attribute in PhixFlow that can be used in the output Stream to populate a Stream Attribute.
• Control, Data, etc.Nodes – that is, types of nodes specific to PhixFlow binary file grammars – will start with an upper case letter.
• Expressions are PhixFlow scripting expressions – see PhixFlow help for more details. All Expressions must be inside curly braces in a grammar file, unless contained in a Script Node.
