[cc: Joe, x3d-public, hanim]

John, like you, am not finding "l_metatarsophalangeal" in current X3D Schema or X3DUOM.  Instead am finding

	l_metatarsophalangeal_1
	l_metatarsophalangeal_2
	l_metatarsophalangeal_3
	l_metatarsophalangeal_4
	l_metatarsophalangeal_5

Close reading of these HAnimJoint names will note the prefixes l_ and r_ are alphabetic, while suffixes _1 _2 _3 _4 _5 are numeric.

However, like you, am nevertheless finding "l_metatarsophalangeal" in current HAnim Specification in both animation examples but also Part 1 Concepts.

[1]	HAnim version 2
    	https://www.web3d.org/documents/specifications/19774/V2.0/index.html

[2]	Part 1:  Humanoid animation (HAnim) architecture, 4 Concepts, 4.9.4 The feet
    	https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/concepts.html#TheFeet

This paragraph has a layout problem, now entered as Mantis

[3]	Mantis 1338: HAnim part 1 clause 4.9.4 has malformed HTML
    	https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/concepts.html#TheFeet

(Am guessing we missed this during prior document review because it was offscreen on the far-right margin.)

Dick, first correction: please advise how we can resolve this layout issue which relates to whitespace, not prose.

Dick, please also monitor the following resolution and let's decide if additional prose is appropriate too.

---

The clause itself reads as follows:

> 4.9.4 The feet
> 
> The names of the Joint objects for the LOA‑2 and 3 feet are specified in Table 4.4.
> 
> Table 4.4 — LOA‑2 and 3 foot Joint object names
> 
> Left foot
> 	l_talocrural 	l_tarsometatarsal 	l_metatarsophalangeal 	l_tarsal_interphalangeal
> 
> Right foot
> 	r_talocrural 	r_tarsometatarsal 	r_metatarsophalangeal 	r_tarsal_interphalangeal

Corresponding joints with _1 _2 _3 _4 _5 appended are found in

[4]	Figure 4.9 — LOA‑4 foot joints
    	https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/concepts.html#f-FootJoints

Joe, second correction:  I think that we missed defining 'alias' values for this difference between LOA-2/LOA-3 and LOA-4.

Proposed fix: define alias correspondences in X3D XML Schema, X3DUOM and corresponding Quality Assurance (QA) diagnostics such as X3D Schematron and X3D Tooltips.

	l_talocrural            	l_talocrural_1
	l_tarsometatarsal       	l_tarsometatarsal_1
	l_metatarsophalangeal   	l_metatarsophalangeal_1
	l_tarsal_interphalangeal	l_tarsal_interphalangeal_1

	r_talocrural            	r_talocrural_1
	r_tarsometatarsal       	r_tarsometatarsal_1
	r_metatarsophalangeal   	r_metatarsophalangeal_1
	r_tarsal_interphalangeal	r_tarsal_interphalangeal_1

Please let me know what you think about these alias additions.  Entered as

[5]	Mantis 1339: missing alias correspondences for foot joints LOA-2/LOA-3 and LOA-4
    	https://www.web3d.org/member-only/mantis/view.php?id=1339

John, if accepted, that change will clear the diagnostic errors you encountered. Thanks for pursuing this tricky problem, am happy to confirm that your diagnosis was exactly on target.

Pretty tricky problem, but appears to have a straightforward solution.  Please advise what you think.
