Custom model: "name" and "namespace" restrictions. Config Properties: documentation need

We have recently created a custom model in alfresco: downloaded the 2.2.1 archetype and edited content-model.xml.

It took as some time to discover that

• the prefix of a namespace can not contain underscore "_" character
• the name of the model can not be "contentModel"

<model name="pr:contentModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

...

</model>

Apologies, is these are not true, or/and documented somewhere.

One question is what alfresco classes parses the models in repository tier, and the alfresco-config in the share tier, so by reading the code we could correct further mistakes.

Meanwhile, in share, there are some configurations with properties like 'evaluator' and 'condition'

e.g. <config evaluator="node-type" condition="cm:content"> ...</config>

      <config evaluator="aspect" condition="pr:myAspectName">...</config>

and further properties

e.g.

force="true"

for-mode="edit" 

Where could we learn more about their usage?

Thanks in advance

There is no explicit code that disallows the underscore as a prefix. But functionality related to the Forms engine will encode the colon of a qualified name as an underscore when transporting it over the wire, as well as decode the first underscore as a colon. This causes issues when you consciously chose to use an underscore in the prefix. This can be seen in places such as QNameFieldProcessor or ContentModelFormProcessor.

I am unaware of any functionality that would interfere with naming a model xy:contentModel. I often use a name as simple as that. Or do you mean the name only be "contentModel" without a prefix? That would be invalid as name is typically required to be a qualified name (QName) - this is the same with name of properties, aspects and types.
