3gpp-drafting

3GPP TDoc Drafting

Use this skill for 3GPP-specific document structure, metadata conventions, and concrete Word style names. For formatting rules (headings, enumerations, notes, tables, figures, citations), see sdo-docx-formatting. For officecli operations (tab-run injection, field codes, bookmarks), see sdo-docx-operations.

Assets

• assets/Tdoc_Template.docx -- canonical Word template with all required 3GPP styles. Copy to ref/Tdoc_Template.docx when initializing a new project (see sdo-project-setup for the common project bootstrap workflow). This is a user-crafted file containing all required styles (B1, B2, NO, NW, TH, TAH, TF, EX, PL, etc.) and is not tied to an official 3GPP release cycle.

References

• references/frontmatter.md -- 3GPP-specific PLAN.md metadata keys.
• references/template-substitution.md -- Jinja2 placeholder substitution for the 3GPP TDoc template.
• references/revision-workflow.md -- 3GPP-specific header structure and copy-rename-patch procedure for revisions.

Moved to sdo-project-setup: project layout, AGENTS.md template, universal project prompt, and set_docx_props.py (now generalized with a --props parameter). Load sdo-project-setup for these common functions.

3GPP style-name mapping

Concrete Word style IDs for 3GPP documents. Use these when applying formatting rules from sdo-docx-formatting.

Abstract name (sdo-docx-formatting)	3GPP concrete style ID	Purpose
body-text	Normal	Main body paragraphs
heading-1	Heading 1	Top-level section heading
heading-2	Heading 2	Second-level section heading
heading-3	Heading 3	Third-level section heading
enum-1	B1	First-level enumeration (en-dash bullet)
enum-2	B2	Second-level enumeration
enum-3	B3	Third-level enumeration (if used)
table-caption	TH	Table caption (above table)
table-header	TAH	Table header row
table-data	TAC	Table data rows
table-note	TAN	Table merged-bottom-row note
figure-para	FL	Paragraph containing image
figure-caption	TF	Figure caption (below figure)
figure-note	NF	Note below figure, before caption
note-main	NO	Last note in a consecutive block
note-continuation	NW	Preceding notes in a block
reference-entry	EX	Each references section entry
code-text	PL	Inline code, function/variable names, filenames

Additional 3GPP-specific styles (no abstract equivalent):

Style ID	Purpose
TDoc-Header	Cover page header paragraphs (TDoc number, date, source, title, agenda item, target)

Heading conventions (3GPP-specific override)

3GPP headings use manual numbering only (never Word auto-numbering). See sdo-docx-formatting/references/headings.md for full rules. The References section is unnumbered and always the last section.
