=> label (container | heading)*

The root of a structure member is a heading, which represents a section of output beginning with a title (the label) and ordinarily followed by content containers or further nested (sub)-sections of output. Unlike heading elements in HTML and other common document formats, which precede the content that they head, heading contains the elements that appear below the heading.

The document root heading, only, may contain a pageSetup element.

The following attributes have been observed on both document root and nested heading elements.

Attribute: creator-version

The version of the software that created this SPV file. A string of the form xxyyzzww represents software version xx.yy.zz.ww, e.g. 21000001 is version 21.0.0.1. Trailing pairs of zeros are sometimes omitted, so that 21, 210000, and 21000000 are all version 21.0.0.0 (and the corpus contains all three of those forms).

The following attributes have been observed on document root heading elements only:

Attribute: creator

The directory in the file system of the software that created this SPV file.

Attribute: creation-date-time

The date and time at which the SPV file was written, in a locale-specific format, e.g. Friday, May 16, 2014 6:47:37 PM PDT or lunedì 17 marzo 2014 3.15.48 CET or even Friday, December 5, 2014 5:00:19 o'clock PM EST.

Attribute: lockReader

Whether a reader should be allowed to edit the output. The possible values are true and false. The value false is by far the most common.

Attribute: schemaLocation

This is actually an XML Namespace attribute. A reader may ignore it.

The following attributes have been observed only on nested heading elements:

Attribute: commandName

A locale-invariant identifier for the command that produced the output, e.g. Frequencies, T-Test, Non Par Corr.

Attribute: visibility

To what degree the output represented by the element is visible.

Attribute: locale

The locale used for output, in Windows format, which is similar to the format used in Unix with the underscore replaced by a hyphen, e.g. en-US, en-GB, el-GR, sr-Cryl-RS.

Attribute: olang

The output language, e.g. en, it, es, de, pt-BR.
