Re: [xml-dev] Naming conventions for a sampling of W3C and ISO XML vocab

Roger, the following resources might be of interest.  Both are

(way) out of date, but provide reasonable samples for the

specified coverage.

Hi Folks,

I am sampling some standard XML vocabularies to see what naming convention they use. Below is what I've compiled thus far. What naming convention do you use?

1. XML Schema: all elements and attributes are camel case. Examples: maxOccurs, elementFormDefault, substitutionGroup.

2. XSLT: all elements and attributes are lower-case, dash-separated. Examples: apply-templates, exclude-result-prefixes, analyze-string.

3. Schematron: most elements and attributes are a single, lower-case word (e.g., assert, rule, pattern). There is an element and an attribute with multiple words (value-of, is-a). There are two elements that use camel case (queryBinding and defaultPhase).

Notice that Schematron isn't consistent in its naming convention. Is that a bad thing? Is it a good thing to have a consistent naming convention?

Why does XML Schema and XSLT have different naming conventions? They are both W3C technologies. Does the W3C not have a policy on naming markup?
